Frequently Asked Questions

How does the color derivation work?

The generator converts your base color to HSL, then derives complementary, analogous, and triadic colors by shifting hue, saturation, and lightness. Primary shades come from lightness adjustments (±15%), secondary from a 30° hue shift, and accent from a complementary or split-complementary angle. Background and text colors are computed to maintain proper contrast ratios.

What is WCAG AA compliance?

WCAG AA requires a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text. The generator checks every text color against its expected background and marks pairs that pass or fail, so you can ship accessible themes with confidence.

Can I use these themes in any framework?

Yes. The CSS variables export works with any project that supports custom properties. The Tailwind export maps colors directly to your tailwind.config.js, SCSS variables integrate into any Sass workflow, and JSON can be consumed by React, Vue, Svelte, or any JavaScript framework.
