Color picker and converter for OKLCH and LCH color space.
oklch() is a new way to define CSS colors. In oklch(L C H) or oklch(L C H / a) each item corresponds as follows:
- L is perceived lightness (0%-100%). “Perceived” means that it has consistent lightness for our eyes, unlike L in hsl().
- C is chroma, from gray to the most saturated color.
- H is the hue angle (0-360).
- a is opacity (0-1 or 0-100%).
Color picker and converter for OKLCH and LCH color space. OKLCH is a new way to encode colors (like hex, RGBA, or HSL):
- OKLCH has native browser support.
- It can encode more colors for modern screens (P3, Rec. 2020, and beyond).
- Unlike HSL, OKLCH always has predictable contrast after color transformation.
- In contrast with LCH and Lab, no hue shift on chroma changes.
- Provides great accessibility on palette generation.
