FAQ
- Why include OKLCH?
- OKLCH is perceptually uniform: equal numeric steps look like equal visual steps. It is the recommended colour space for design tokens and tonal palettes in modern CSS.
- Why can an extreme scale stop have lower chroma?
- Some OKLCH values fall outside sRGB. The scale reduces chroma at light and dark extremes before conversion instead of clipping channels and silently shifting the hue.
