Questions fréquentes
›What color formats are supported?
HEX, RGB, HSL, OKLCH and named CSS colors. Conversions happen instantly in both directions.
›What is OKLCH?
OKLCH is a perceptually uniform color space supported by modern browsers — great for accessible palettes and consistent lightness across hues.
›Why use OKLCH instead of HSL?
HSL lightness varies wildly between hues (yellow at 50% looks much lighter than blue at 50%). OKLCH fixes this — same L means same perceived lightness.
›Are alpha values supported?
Yes — RGBA, HSLA and 8-digit HEX with alpha all work.
›Is the converter free?
Yes — fully free, no signup.
