Chapter 2 — Colour

What is Colour?

Colour is what we see when light reflects from objects into our eyes. In art we treat colour as a visual quality that artists use to describe form, light, mood and atmosphere. Colour depends on three main attributes: hue, which is the name of the colour such as red or blue; value, which describes how light or dark a colour is; and saturation, which tells how pure or dull the colour appears. Observing colour means noticing subtle differences: the same blue under warm light looks different from blue in shadow. In painting, pigments follow subtractive mixing rules: mixing two pigments usually makes a darker or duller result. Colour also helps separate foreground from background and can suggest temperature — warm colours like red and orange advance toward the viewer, while cool colours like blue and green recede. Learning to see these qualities trains the eye to make better choices when creating artworks. Artists plan colour to guide attention, show form, create harmony or tension, and express feeling.

Practical classroom work begins with looking exercises: matching colour swatches to objects, naming hues, and making small swatches that change in value and saturation. These small studies teach control over the painting medium and start the habit of deliberate colour choice rather than guessing. Students will also discuss simple examples from everyday life where colour communicates meaning such as traffic lights or clothing signals. By the end of this topic, students should be able to describe the main attributes of colour and explain why colour matters in visual communication.

Primary, Secondary and Tertiary Colours

The colour wheel organises colours around a circle to show their relationships. Primary colours are pigments that cannot be mixed from other colours. In paint, traditional primary pigments are red, yellow and blue. When two primaries are mixed, they make secondary colours: red + yellow = orange, yellow + blue = green, blue + red = violet. Tertiary colours are made by mixing a primary with an adjacent secondary, producing hues such as red-orange or blue-green. The wheel helps predict results of mixing and to choose harmonious or contrasting combinations. Learning the wheel allows a student to plan colour mixes rather than relying on trial and error.

In the classroom, students practice by making a simple wheel: paint six segments for primaries and secondaries, then add three tertiary blends between each pair. This exercise teaches control of proportions when mixing. Teachers emphasise clean mixes by using small amounts of paint and cleaning brushes between colours to avoid muddy results. The wheel also clarifies why mixing all three primaries tends toward brown: pigments subtract wavelengths and combine impurities. Students should compare a painted wheel with printed wheels they see in books or on devices; printed colours use light mixing (additive) and may appear brighter. By the end of this topic, students should comfortably name and mix primary, secondary and tertiary colours and understand their positions on the wheel.

Tints, Tones and Shades

Tints, tones and shades explain how to change a colour's value and saturation. A tint is made by adding white to a colour, making it lighter and often less saturated. A shade is made by adding black, making the colour darker and deeper. A tone is made by adding grey (a mixture of black and white) or a complementary colour, which reduces saturation without making the colour too warm or too cool. Artists use tints to paint highlights and create distance, shades for shadows and weight, and tones for subtle variations in surfaces and skin. Practicing these changes helps students control mood and form in a painting.

Classroom exercises include painting a value bar: one row shows a colour with increasing white added to the right; another row shows increasing black to the right. A middle row shows tones made by adding grey or small amounts of the complementary colour. Students learn to mix small increments precisely and to label swatches. Teachers show how using too much black can make colours look lifeless, so adding a complementary colour to create tone often yields richer, more natural results. Observational tasks ask students to match tints and shades seen on real objects, such as a white cloth draped over a coloured object or a shadowed coloured surface. Mastery of tints, tones and shades gives students the tools to model three-dimensional form and subtle lighting with paint.

Warm and Cool Colours

Warm and cool labels help artists decide how a composition will feel and how space will be suggested. Warm colours — reds, oranges, yellows and their warm mixtures — are usually felt as active, energetic and nearer to the viewer. Cool colours — blues, greens, violets and their cool mixtures — are commonly experienced as calm, restful and often more distant. This basic idea is widely used: a warm foreground against a cool background will look like it advances toward us, and cool distant hills will recede. But the effect depends on context, value and saturation as well as the simple warm/cool label. A very bright cool colour can still feel close if it has high saturation and value, while a muddy warm colour may not advance.

Practical lessons train students to make deliberate warm and cool choices. Exercises include painting the same small scene twice: once using predominantly warm colours for most elements, and once using predominantly cool colours, then comparing moods. Another exercise asks students to take one hue (for example green) and make two versions — one warmed slightly with tiny red or yellow additions, and one cooled with tiny blue additions — to see subtle shifts in how the colour reads. Discussions should point out that temperature is relative on the wheel: some blues are warmer (blue with a touch of red) and some greens are cooler (blue-green). Teachers also show how warm highlights with cool shadows can enliven a portrait, or how cool midtones with warm accents can create tension in a composition. Students practise arranging warm and cool zones on thumbnails to plan where they want attention and spatial depth. By mastering warm and cool relationships, learners gain a powerful tool to control mood, create depth and direct the viewer’s eye in their artworks.

Complementary and Contrasting Colours

Complementary colours are pairs that sit opposite each other on the colour wheel: red and green, blue and orange, yellow and violet, for example. When placed next to each other, complements produce a strong visual contrast and can make each other appear brighter because of the way our eyes compare neighbouring hues. When mixed together in pigment, complements tend to neutralise each other and produce greys, browns or muted tones, because each pigment absorbs parts of the light spectrum the other reflects. Artists use both effects: side-by-side placement for vibrancy and mixed complements to create subtle, natural shadows or to tone down a colour without using black.

Understanding contrast more broadly helps students control emphasis. Contrast may be in hue (complementary or very different colours), value (light vs dark), or saturation (bright vs muted). High contrast draws attention and can create a focal point; low contrast produces calm, unity, or background space. Classroom activities include creating a small study where one colour dominates and its complement is used sparingly as an accent to see how attention is directed. Another useful exercise is making a series of swatches where a base hue gradually receives increasing amounts of its complement, showing how the base becomes less saturated and moves toward grey or brown. Teachers guide students to use complements in mixing shadows: instead of adding pure black, adding a small amount of the complementary colour keeps the shadow lively and related to the local colour. Students also learn to watch for unwanted colour shifts when complements mix on the palette or on the painting surface and to clean brushes carefully. By practicing both placement and mixing of complementary colours, learners gain confident control over vibrancy, harmony and subtle desaturation in their work.

Analogous and Monochromatic Schemes

Analogous colour schemes use groups of colours that lie next to each other on the wheel, such as yellow, yellow-green and green. Because these hues share similar base components, they create a natural sense of harmony and are easy to balance without harsh contrasts. They are often chosen when the artist wants a unified, comfortable mood. Monochromatic schemes use variations of a single hue through tints, tones and shades; this approach removes hue variation as a factor and relies on value and saturation to create interest. Both schemes teach restraint and careful control of value to keep the composition readable and expressive.

In practice, students begin by choosing a narrow slice of the wheel for an analogous study and limiting themselves to three to five hues plus neutrals. Exercises include painting a landscape or still life with only analogous colours, testing how to separate objects using value rather than hue. For monochrome, students paint a study using one pigment plus white and black to create different values and saturations. Teachers emphasise that in both schemes accents can be used to prevent monotony: a small neutral (grey, off-white or brown) or a tiny complementary touch can increase visual interest. Classroom tasks also include planning thumbnails showing which area will hold most contrast and where values will shift. Students practise making a palette card with exact mixes and small swatches to maintain consistency across the painting. Critique discussion focuses on whether value relationships are clear enough: in monochrome pieces, value contrast is especially important since hue cannot separate forms. By working with analogous and monochrome schemes, learners develop skills in subtle variation, unity and planning, preparing them to use limited palettes confidently in design and craft projects.

Colour Mixing Techniques with Tempera/Poster Paint

Mixing paint is a skill of small steps, cleanliness and testing. Tempera and poster paints behave similarly: they dry quickly and can change slightly in tone as they dry. Start with a clean palette and small amounts of paint; place primary colours and white separately so you can mix fresh batches without contamination. Use a palette knife or flat brush to blend; mix thoroughly to observe the true resulting hue. Always add the stronger or darker pigment in small increments to a larger amount of the lighter pigment when attempting a repeatable mix. Measuring by eye becomes easier with practice, but students should record rough ratios (for example 2:1) on a palette card so they can reproduce the mix later.

For tints, add white gradually and remember white can cool a colour and reduce saturation. For tones, mix the colour with a neutral grey or a small touch of the complementary colour instead of black to maintain richness. For shades, a tiny amount of black can be used, but often mixing a darker hue (such as ultramarine instead of black) produces more natural results. Because tempera and poster paints thin slightly when water is added, test swatches on scrap paper and let them dry to judge the final colour. Use separate water pots and paper towels to keep brushes clean and avoid muddying colours. Prepare a mixing chart with columns for base colour, tint, tone and shade, and leave space for notes on drying changes. Teachers should demonstrate cleaning techniques and safe disposal of water. Classroom practice includes measured mixes: students reproduce a colour using noted parts, paint several swatches to check consistency, and correct as needed. By mastering these techniques, students will gain reliable control over the colours they plan to use in their final compositions.

Creating Depth with Colour (Atmospheric Perspective)

Atmospheric perspective is a method artists use to show depth by changing colour and value rather than relying only on size or overlap. As distance increases, objects are seen through more air and particles; they therefore appear lighter, less saturated and often cooler in hue. Closer objects remain richer in colour, darker in value and usually warmer in temperature. Artists use this predictable shift to make landscapes and city scenes feel three-dimensional on a flat surface. The technique also involves reducing detail and softening edges for distant forms so the eye reads them as far away.

In the classroom, begin with observation: compare colours of a nearby tree, a middle-distance building and distant hills on a clear day. Note that the hills often appear blue-grey and faint, even if they are green up close. Practical exercises include a three-plane painting practice: establish foreground with strong warm colours and high contrast, middle ground with moderate saturation and contrast, and background with pale, cool washes. Use glazing or thin washes for background planes so earlier layers remain visible and soft. Another useful exercise is to paint a row of identical shapes placed at equal distances but coloured progressively from warm/dark to cool/light to see how the same shape appears to recede. Teachers should stress value control: if background values are too dark, atmospheric effect fails; if foreground lacks contrast, the composition looks flat. Students should also learn to use complements subtly in shadows of foreground objects to maintain colour richness while not competing with the cooler background. Finally, show how atmospheric perspective changes with weather — on a hazy day contrasts are reduced more strongly, while on a clear day mid-distance contrasts remain visible. Practising these variations strengthens observational skills and helps students plan believable spatial effects in their paintings.

Colour and Emotion

Colour choices influence how viewers feel about an artwork. Certain colours commonly evoke particular feelings: red often communicates energy, excitement or danger; blue can suggest calmness, sadness or coolness; yellow tends to feel cheerful or urgent depending on saturation; green often links to nature and rest. Artists use these associations to support a story or mood in a painting. However, colour meanings are not fixed — cultural background, personal experience and context alter how a colour is read. For instance, white may mean purity in one culture and mourning in another. Students should learn both common associations and the idea that meaning can be changed by context, contrast and placement.

Classroom activities centre on experimenting and explaining choices. One practical task is the mood study: choose a simple subject such as a chair or vase and paint three versions using different palettes to evoke joy, calm and tension. Ask students to note which colour combinations, saturation levels and value contrasts they used and why. Discuss how saturation affects emotion — highly saturated colours feel lively and intense, while muted colours feel restrained or melancholic. Value contrast also matters: dramatic contrasts create tension or focus, while low contrast creates harmony and quietness. Teachers should encourage precise vocabulary when discussing work: rather than saying "the colours are nice," ask students to describe hue, temperature, saturation and value and how these choices serve the subject. Another exercise is to reinterpret a famous image (photograph provided by teacher) in a new palette to see how mood shifts. Over time, students learn to choose palettes deliberately to support narrative, and to explain their choices in short notes accompanying their artworks. This reflective habit connects technical colour skills to expressive goals and prepares students to make purposeful artistic decisions.

Colour in Pattern, Fabric and Crafts

Applying colour to patterns, fabrics and simple crafts requires thinking about repeat, scale, and how colours read at different distances. Small, closely repeated motifs read as texture from afar and need clearer contrasts so they do not disappear; larger motifs can hold subtler colour shifts and more detail. In textile and craft work, a reduced palette often gives a stronger result: choose two or three dominant colours and one neutral to balance the design. Consider also the ground colour and how it will interact with motif colours — a bright motif on a dark ground can appear crisp, while a low-contrast motif may blend and lose clarity.

Classroom projects may include block printing, fabric painting, rangoli designs or simple beadwork. For block printing, students learn to plan layers: print lightest colours first and darkest last, and test registration so repeats align. For fabric painting, practise choosing pigments that are colourfast and safe for use on cloth, and consider how wet-on-wet techniques will affect adjacent colours. Students should make small colour mock-ups (swatch strips) to see how the motif colours work against the chosen ground at the intended viewing distance. Teachers also introduce concepts like complementary accents to make a central motif pop, and neutral anchors to rest the eye. Another useful exercise is designing a repeating tile: draw a single motif and imagine how it repeats in a grid, then choose a limited palette and test how the repeats look when placed together. Discuss practical concerns such as washing or fading for wearable crafts, and simple fixing methods if needed. Through these exercises students learn to control colour for decorative arts, balancing creativity with functional choices for craft materials and viewing conditions.

Planning a Colour Composition

Successful colour work starts with a plan. Before beginning a final painting, make small thumbnail sketches to test composition and where the eye should travel. Decide on a dominant colour, one or two supporting colours, and a small accent colour for focal points. Create palette swatches on a plan sheet and label mixes with rough proportions so you can reproduce them. Mapping values early is essential: a clear value hierarchy makes forms readable even when hues are limited. Identify which areas will hold the highest contrast and reserve these for the focal point. Some students find it helpful to make a value-only study first using charcoal or grey washes to ensure readability.

Practical classroom routine: start with three thumbnails exploring different placements and palette choices; then produce a palette card with 4–6 swatches showing base colour, tint, tone and shade and brief notes such as "2 parts yellow ochre + 1 part red for warm midtones." Paint small test swatches on scrap paper, let them dry and compare to the intended objects or reference photos. Use a light underpainting or wash to set the values and cool/warm zones before layering final colours. Teachers emphasize saving the brightest contrast for the focal area and avoiding uniform high saturation across the whole canvas which can confuse the eye. Also advise on practical matters: mix slightly more paint than needed and label jars if working over several days to keep colour consistent. Encourage flexibility — plans can change during execution when better ideas appear — but a clear starting plan prevents random decisions and reduces the chance of muddy colours. By practising planning sheets, students develop a disciplined workflow and gain confidence in turning colour ideas into controlled final works.

Evaluation and Critique of Colour Choices

Learning to evaluate colour choices helps students improve faster. Critique should start with clear description: name the dominant colours, point out where contrast is highest and note areas of low or high saturation. Move on to analysis: does the palette support the subject and intended mood? Are the values arranged so forms read clearly? Are accents placed effectively to guide the eye? Conclude with constructive suggestions: what to strengthen, what to soften, and simple ways to adjust mixes or values. The goal is to be specific and helpful rather than vague praise or criticism.

In class, structure peer critique with a short checklist: one observation of strength, one question, and one suggestion. Model helpful language such as "The warm foreground helps direct attention; consider lightening the background to increase depth" rather than "Make the background lighter." Teach students to keep an open mind and to test suggestions with small changes rather than large overhauls. Also encourage self-critique: after a painting, write a short note answering three prompts — what worked, what surprised me, and what I would change next time. Teachers can keep a record of critiques and follow-up actions so students see their progress across projects. Another useful activity is comparative critique: show two similar works that use different palettes and ask students to discuss which is more effective and why. Over time, critique trains visual vocabulary and judgement, enabling students to explain colour decisions clearly and to make targeted improvements in their work.

Practical Project: Still Life Using Learned Colour Principles

The still-life project applies the unit's colour lessons to a complete artwork. Students select 3–5 objects with varied shapes and colours and arrange them to create a clear focal point. Begin with a plan sheet: three thumbnail compositions, a chosen limited palette with swatches, and a value map indicating where the light source falls and where the highest contrasts will be. Decide which colours will be dominant, which will be secondary, and a small accent colour to draw attention. Prepare a mixing chart so the exact hues and tints can be reproduced during painting.

Execution steps: start with a light underpainting or drawing to map values; block in midtones to establish local colours; refine edges and model forms using tints for highlights and tones for mid surfaces. Use complementary colours sparingly for lively shadows instead of pure black. Pay attention to warm and cool relationships to suggest depth — warmer, stronger colour in the foreground and cooler, subdued tones for background elements. Maintain clean brushes and consistent mixes by mixing enough paint and labelling swatches if working over several days. Teachers should visit each student to suggest small adjustments and to check value relationships early, before details are added. Assessment looks for evidence of planning, controlled mixing, readable values, and deliberate colour choices that support the composition. After completion, hold a short critique where each student explains their palette decisions and writes a two-sentence reflection on what they learned and what they would change. This project integrates technical mixing skill, observational practice and aesthetic decision-making to demonstrate mastery of the unit's key ideas.
