About HSL and OKLCH

HSL describes a color by hue (0–360 on the color wheel), saturation and lightness. It is easier to reason about than raw channels — rotating a hue or dimming a color is a single number change — which makes it popular for theming.

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, hsl(262, 83%, 58%) in HSL is oklch(0.542 0.245 293) in OKLCH. Paste any value above — conversion is instant, runs entirely in the browser, and carries alpha through when the color has one.
