FAQ
How do I generate a harmonious color palette?
For UI design, avoid fully random colors — they rarely form harmonious palettes. Use techniques: analogous (adjacent hues on the color wheel), complementary (opposite hues, 180° apart), triadic (3 evenly-spaced hues at 120°), or monochromatic (same hue, different lightness). Design tools like Coolors, Adobe Color, and Paletton generate these programmatically. For design systems, start with one brand color and derive shades at fixed lightness steps.
