About RGB and OKLCH

RGB lists red, green and blue as numbers from 0 to 255, matching how screens mix light. It is the format most APIs, canvas code and design tools expect, and rgba() adds an opacity value from 0 to 1.

OKLCH is the perceptual color space from CSS Color 4 — lightness, chroma and hue that track how colors actually look. Equal lightness values appear equally bright, which makes it a good base for design systems and generated palettes. Every modern browser supports it.

For example, rgb(124, 58, 237) in RGB is oklch(0.541 0.247 293) in OKLCH. Paste any value above — conversion is instant, runs entirely in the browser, and carries alpha through when the color has one.
