Colour theory is the set of ideas that explains how colours are made, how they relate to each other and how they affect the way people feel and behave. It covers the colour wheel, colour harmony (combinations that look good together), contrast, and the meaning or psychology of colour. In animation and game design, colour theory is a tool for guiding attention, setting mood, telling story and giving players information.
The basics – primary, secondary and tertiary colours, warm and cool colours, hue, saturation and value – were introduced in Colour Theory, Texture, Composition and Layout. This post focuses on why colour theory matters in animated and interactive work, and on designing colour that every player can read.

Quick review: colour harmonies
- Complementary: colours opposite on the wheel (blue and orange). Maximum contrast – great for making a hero or a pickup stand out.
- Analogous: neighbours on the wheel (yellow, yellow-orange, orange). Calm and unified – great for backgrounds and moods.
- Triadic: three evenly spaced colours (red, yellow, blue). Lively and balanced, common in children’s games.
- Monochromatic: one hue in different values and saturations. Stylish and moody, useful for flashbacks or menus.
Why colour theory is important in animation and game design
1. It guides the eye
Players must spot what matters in a fraction of a second. Designers give important objects higher saturation, brighter value or a complementary colour against a muted background. Many games paint climbable ledges or interactive objects in one consistent colour so players find the path without a tutorial.
2. It sets mood and tells story
Animators plan a colour script: a strip of small paintings that shows how the colour of a film changes scene by scene. Warm golden light can signal safety and happiness; cold blues can suggest loneliness or mystery; a sudden shift to red can announce danger. Games do the same between levels, or between day and night.
3. It communicates information
Colour is part of the game’s language: green health bars, red damage numbers, gold for rare rewards, team colours in multiplayer. Once these rules are set, they must stay consistent – or players will make mistakes.
4. It builds identity and brand
A strong palette makes a game or animated series recognisable from a single screenshot. Think of a series you know well: you can probably name its main colours.
5. It links to culture
Colours carry different meanings in different places. White is linked to weddings in many Western countries but to mourning in parts of Asia; red can mean luck and celebration in Chinese culture. Designers creating for a worldwide audience research these meanings (we look at culture more closely later in this module).
6. It affects accessibility
About 1 in 12 men and 1 in 200 women have some form of colour vision deficiency (colour blindness), most often difficulty telling red from green. If a game uses only red versus green to show enemies versus friends, many players cannot play fairly.


Designing colour for everyone
- Never use colour as the only signal: add shapes, icons, patterns or text (for example a skull icon on enemies, a tick for correct answers).
- Check value contrast: turn your screenshot greyscale. If important things disappear, increase the difference in lightness.
- Offer a colour-blind mode or custom colour settings where possible.
- Test with free colour-blindness simulators before release.
This video from Tiny Shiny Things shows how an indie developer uses colour theory (and shape language) to make a game readable and appealing:
Example
A small team is making a cartoon game about a reef clean-up. Their colour plan looks like this:
| Part of the game | Colour choice | Reason |
| Healthy reef levels | Analogous blues, teals and soft greens | Calm, natural and unified. |
| Player’s diver | Bright orange suit | Complementary to the blue water, so the player is always visible. |
| Rubbish to collect | Saturated yellow with a white outline and a sparkle icon | High contrast plus a shape cue that works for colour-blind players. |
| Polluted areas | Desaturated brown-grey | Shows the damage visually; colour returns as the player cleans up. |
| UI panels | Dark navy with white text | Strong value contrast for readability. |
The colour itself becomes a reward: as the player cleans each area, the reef “re-colours”, turning a game mechanic into a visible story.
Exercise
- Define colour theory in one or two sentences, then list four reasons why it is important in animation and game design.
- Choose a game or animated film. Describe its palette and explain how the colours support the mood or story.
- Create a colour plan (like the table above) for a game idea of your own. Include at least one complementary pair.
- Take a screenshot of a game and convert it to greyscale. Is the important information still clear? Suggest two changes that would improve accessibility.
