A triadic color scheme is a set of three colors evenly spaced on the color wheel - every 120°. Creates energetic, balanced color compositions. Just choose one base color - the tool calculates the remaining two.
Triadic color scheme - basics
On the 360° color wheel: base color (0°) + color 2 (120°) + color 3 (240°). Example: red (#FF0000) → yellow-green (#00FF00) → blue (#0000FF). The scheme is vivid and contrasting - each color is as far away from the others as possible. Used when diversity and dynamics are important.
Other color harmony schemes
Analogous: 3 adjacent colors (30° spacing) – calm, natural. Complementary: 2 colors opposite (180°) – maximum contrast. Tetradic (square): 4 colors every 90° - rich, complex. Split-complementary: color + 2 adjacent to the complementary - less contrast than triadic.
Adjusting Saturation and Brightness
Pure triadic colors may be too intense for UI applications. Modifications: reduce the saturation to 60-70% (pastel tones). Change the brightness: 1 dark color (dominant), 2 light colors (accents). Add tinted (with white) and shaded (with black) versions for the design system. HSL makes these modifications easy.
Using a triadic scheme in design
60-30-10 rule: 60% dominant color (background, large areas), 30% secondary color (tabs, sections), 10% accent color (CTA, highlights). Avoid using all 3 colors at full intensity at the same time - 1 dominates, the rest support.
FAQ
When is a triadic pattern appropriate and when is it not?
Good for: posters, illustrations, energy branding, children's materials, sports and gaming. Avoid in: corporate software (too vibrant), minimalist design, medicine (calm colors). Triadic works better when at least 1 color is subdued or light.
How to choose a base color for a triadic scheme?
Start with the brand color. Generate a triadic and check if the resulting colors match your industry. If the base is blue – you will get orange and green. If yellow - magenta and cyan. Test different base shades of the same color.
How to check the availability of a triadic schema?
Check the contrast of each color/background pair (WCAG "color contrast" tool). Triadic diagrams may have poor contrast between them - important for the text. Color blindness: use the color blindness simulation tool (Coblis). Type of protanopia/deuteranopia: red-green blindness most common (8% of men).
What is the color wheel and where does it come from?
Color theory: Newton (1666, prism and spectrum), Goethe (color wheel, 1810), Itten (Bauhaus, 1961 - the most popular 12-color scheme). Kolo RYB (red-yellow-blue): traditional painting. RGB wheel: screens (additive). CMYK circle: printing (subtractive). The tool uses the HSL (perceptual) model.
How to use triadic colors in CSS?
Define as CSS variables: :root { --color-1: #E63946; --color-2: #2A9D8F; --color-3: #E9C46A; }. Then use by var(--color-1). Dark mode: use oklch() with adjusted lightness. Design token: export to Figma, Style Dictionary or Tailwind config.
