Colour family
Hue
The name or family of a colour, such as red, yellow, green or blue. Changing hue means moving to a different colour family.

Understand colour theory.
Colour theory gives artists a practical language for seeing, mixing and combining colour. Learn how hue, value, chroma and temperature work together, then use colour relationships to build palettes with intention.
What is colour theory? Colour theory is a framework for describing how colours relate, how they can be mixed and how combinations influence the appearance of an artwork. It brings together the colour wheel, colour attributes, contrast and harmony. It is a guide for making informed choices, not a rigid set of rules.
01 · Learn the language
Four ways to describe colour
Artists often use these terms together, but each describes a different quality. Knowing the difference makes it easier to explain what a colour needs.
Light to dark
Value
How light or dark a colour appears. Value contrast helps create form, depth, focal points and legibility.
Intensity
Chroma or saturation
How vivid or muted a colour appears. High-chroma colours feel intense; lower-chroma colours feel quieter or more neutral.
Visual impression
Temperature
Whether a colour reads as warmer or cooler in context. Temperature is relative: a red can lean warmer or cooler compared with another red.
Try this: when a colour feels wrong, ask whether its hue, value, chroma or temperature needs to change. Adjusting the right attribute is often more effective than adding more paint at random.
02 · Map the relationships
Read the colour wheel
A colour wheel arranges hues around a circle so you can spot neighbours, opposites and intermediate colours. It is a model for understanding relationships, not a promise that all pigments mix identically.
Primary colours
Traditional starting points
In the traditional artist's wheel, red, yellow and blue are presented as primary colours for introducing basic colour relationships.
Secondary colours
Between the primaries
Orange, green and violet sit between the primary colours in the traditional model and are commonly taught as mixtures of two primaries.
Tertiary colours
In-between hues
Tertiary colours are intermediate hues such as yellow-orange or blue-green. They help create more nuanced palettes than a few basic colours alone.
Remember: colour models differ. Digital light uses an additive model, while paint mixing depends on pigments and their properties. The traditional wheel is useful for learning relationships, but real mixtures can be more complex.
03 · Build combinations
Colour relationships and palettes
A palette is a deliberate group of colours selected to work together. The wheel helps you predict whether a combination will feel harmonious, energetic, quiet or high-contrast.
Complementary
Colours opposite one another on the wheel, such as red and green or blue and orange. They create strong contrast and can make each other appear more intense when placed side by side.
Analogous
Colours next to one another on the wheel, such as red, orange and yellow. They usually share a visual relationship and can create a cohesive, unified palette.
Triadic
Three hues spaced around the wheel. A triadic palette can feel lively and balanced when one colour leads and the others play supporting roles.
Monochromatic
One hue explored through different values and chromas. This can create a unified image with emphasis on light, shadow and subtle variation.
Earthy and muted
Lower-chroma colours, neutrals and earth tones can soften contrast and support natural, atmospheric or vintage-inspired work.
High contrast
Strong differences in value or hue draw attention. Reserve the strongest contrast for the focal point when you want a clear visual hierarchy.
Practical rule: choose a dominant colour first, then add supporting colours. Equal amounts of every hue can compete for attention.
04 · Adjust the colour
Tints, shades, tones and value
You can change the appearance of a hue without choosing a completely different hue. These changes are useful for highlights, shadows, atmosphere and subtle palette variation.
Tint
A hue mixed with white in traditional paint terminology. Tints appear lighter and are useful for highlights, pastel palettes and airy passages.
Shade
A hue mixed with black in traditional paint terminology. Shades deepen a colour, though the result depends on the pigments used.
Tone
A hue softened with grey, or reduced in intensity through mixing. Tones can help a palette feel more restrained and cohesive.
Value scale
Plan light and dark before detail
LightMidtoneDark
A painting can use many beautiful hues and still feel flat if the values are too similar. Squint at the reference or make a small grayscale study to check the overall structure.
Chroma scale
Vivid to muted
To quiet an intense colour, mix thoughtfully with a compatible complementary or neutral pigment. Results depend on the pigments, so test small mixtures instead of assuming a universal formula.
05 · Warm and cool
Colour temperature is relative
Warm colours often suggest sunlight, energy or closeness, while cool colours can suggest shade, distance or calm. These are common visual associations, not fixed rules.
Warm and cool within one hue
A yellow that leans toward orange may feel warmer than a greenish yellow. A blue that leans toward violet can feel different from a blue that leans toward green.
Use temperature to guide depth
Temperature contrast can help separate foreground and background or create atmosphere, but value, saturation and context also affect the result.
06 · Mix with intention
What happens when pigments mix?
Paint mixing is subtractive: pigments absorb some wavelengths and reflect others. A mixture is influenced by the pigments' undertones, transparency, strength and proportions.
Start with small amounts
Add a little of the stronger pigment to the larger mixture. This gives you more control than trying to reverse an overpowered mixture.
Expect pigment differences
Two paints with the same colour name may mix differently because the pigments and formulations differ. Test the actual paints you own.
Mix neutrals deliberately
Complementary pigments can reduce chroma and create nuanced neutrals. The exact result depends on pigment selection and proportions.
Make a swatch record: label each test with the paint names and approximate proportions. A simple mixing chart becomes a useful personal reference over time.
07 · Put it into practice
Plan a palette step by step
A clear palette starts with the purpose of the image. Use this sequence to make deliberate choices before you commit colour to the artwork.
Choose the mood
Decide whether the work should feel energetic, quiet, warm, cool, natural or dramatic.
Select a relationship
Try complementary colours for contrast, analogous colours for unity, or monochromatic colour for value-led work.
Set value structure
Choose where the lightest lights, midtones and darkest darks will sit.
Test and adjust
Make small swatches, check the palette together and adjust temperature or chroma as needed.
| Goal | Palette starting point | Watch for |
|---|---|---|
| Bright focal point | One high-chroma colour with quieter supporting colours | Too many equally intense colours competing for attention. |
| Calm landscape | Analogous greens, blues and earth colours | Values becoming too similar across foreground and distance. |
| Dramatic contrast | Complementary hues plus a clear light-dark structure | Colour contrast overpowering the subject or composition. |
| Soft, vintage mood | Muted colours, warm neutrals and controlled accents | Reducing chroma so much that the image loses a clear focal point. |
