Frequently asked questions

No. This tool works in the REVERSE direction: only when you enter a SINGLE base color and select a harmony scheme (complementary/triadic/analogous etc.), it GENERATES a harmonious palette from that color. There is no multi-color input, harmony score calculation, or "are these colors harmonious" analysis.
