Frequently Asked Questions
How do the color harmony rules work?
Harmonies are calculated using exact mathematical angular offsets on the 360° HSL color wheel. For example, complementary colors are 180° apart, and triadic colors sit 120° apart.
Can I lock specific colors while generating new ones?
Yes! Simply click the lock icon on any swatch. When you press the spacebar or hit "Generate", locked colors stay intact while remaining slots regenerate harmoniously.
How do I copy or export the palette?
Click any individual color to copy its HEX code, or use the Export modal to get ready-to-use CSS variables, Tailwind tokens, or JSON format.
Does this tool send my palettes to an external server?
No! All color calculations, harmonies, and exports happen 100% locally in your browser with zero network tracking.
