Colour Harmony Wheel
Explore colour harmonies on the wheel — complementary, analogous, triadic and more — to build schemes that work.
Why some colour combinations just work
Colours that look good together are not random — they sit in specific relationships on the colour wheel, and those relationships are what colour theory calls harmonies. This shows the harmonies for a chosen colour, so you can build a scheme on a proven relationship rather than guessing which colours belong together.
The main harmonies
Each harmony is a rule for picking colours by their position on the wheel, and each has a characteristic feel:
| Harmony | How it's picked | Feel |
|---|---|---|
| Complementary | Two colours opposite each other | High contrast, vibrant |
| Analogous | Colours next to each other | Calm, cohesive |
| Triadic | Three evenly spaced colours | Balanced, lively |
| Split-complementary | A colour plus two beside its opposite | Contrast, less tension |
| Tetradic | Two complementary pairs | Rich, harder to balance |
| Monochromatic | One hue, varied lightness | Elegant, unified |
Complementary pairs create striking contrast, useful for making an accent pop; analogous schemes feel harmonious and restful; monochromatic is the safest and most elegant, using one colour at different lightnesses.
Using harmonies in practice
A harmony gives you a starting relationship, not a finished palette — you still choose which colour dominates and which acts as an accent, and you usually adjust the raw harmony colours to be more usable, since the pure wheel colours can be too intense for a whole interface. A common and reliable approach is to let one colour dominate, use a harmonious partner sparingly as an accent, and lean on neutrals for most of the design. Understanding the harmonies is what lets you reason about colour deliberately — knowing why a combination clashes or sings — instead of trying colours at random until something looks right.
Common questions
What is a colour harmony?
A relationship between colours based on their positions on the colour wheel — like complementary or analogous — that tends to look good together.
Which harmony should I use?
Complementary for striking contrast and pop, analogous for a calm cohesive feel, monochromatic for elegant safety. It depends on the mood you want.
Does a harmony give me a finished palette?
No — it gives a starting relationship. You still choose a dominant colour and accents, and usually soften the pure wheel colours to be usable across an interface.
