Nothing you paste leaves this page

The conversion runs in this browser tab. Nothing is sent to Sellstamp or anyone else, which matters for configuration files, customer exports and tokens.

OKLCH

OKLCH is the CSS colour format built on how people perceive lightness, so two colours with the same L look equally light, which HSL does not guarantee. The conversion follows the CSS Color 4 specification, checked against its published values for the sRGB primaries.

Questions

What is OKLCH for?

Building palettes where shades are evenly spaced to the eye. Every current browser supports it in CSS.
