Frequently asked questions
Which harmony should I use?
Analogous palettes feel calm, complementary palettes feel energetic, and triadic palettes feel balanced and vibrant.
How are the colors calculated?
The tool rotates the base hue on the color wheel and adjusts lightness or saturation to build each scheme.
Can I lock a color I like?
Copy any swatch you want to keep, then generate again around a new base for more options.
How many colors per palette?
It depends on the harmony — from two for complementary up to five for monochromatic and tonal sets.
Are palettes free to use?
Yes. The colors you generate are yours to use in any personal or commercial project.
