Frequently asked questions
How are the palettes generated?
Design Cat picks colors by color-harmony rules on the HSL wheel — analogous takes neighboring angles, complementary the opposite 180°, triadic an even 120° — then layers a lightness ramp on top for a set that's both contrasty and coordinated.
How do I keep a color and reroll the rest?
Click the lock icon on that swatch. When you press Space or hit Shuffle, locked colors stay and only the others regenerate.
Can I export it for code?
Yes. Copy all gives a comma-separated HEX list; Copy CSS vars gives a ready :root { --color-1: … } block to paste into your stylesheet.
