Triadic/Tetradic Palette Builder
Generate color-wheel harmony schemes from one base color.
Color-wheel harmony schemes
Triadic and tetradic schemes use three or four colors evenly spaced around the wheel, producing vibrant, balanced palettes that feel intentional. This builder generates those harmony schemes from one base color, with the full set previewed together.
Evenly spaced hues give you variety without clashing, which suits illustrations, charts, and bold brands. Pick a base color, choose triadic or tetradic, and copy the coordinated hex values that result.
Balanced schemes
Evenly spacing three or four hues around the wheel produces vibrant palettes that still feel coherent. The palette is built in your browser and never uploaded.
Frequently asked questions
What does the triadic tetradic palette builder do?
It rotates your base hue by 120-degree or 90-degree intervals to create harmony palettes.
What is the difference between triadic and tetradic?
Triadic uses three hues 120 degrees apart. Tetradic here uses four hues 90 degrees apart, a square scheme, all at the base color's saturation and lightness.
How should I use a triadic palette?
Pick one dominant color and use the other two sparingly as accents. Three equally strong colors tend to compete.
Why do some generated colors look too bright?
Every swatch keeps the base color's saturation and lightness, and some hues, like yellow, look brighter at the same values. Tone them down with the HSL wheel if needed.
