About OKLCH Color Picker

OKLCH Color Picker lets you choose colors by lightness, chroma and hue in the OKLCH color space and converts pasted HEX, RGB or HSL values to OKLCH. It shows the closest sRGB fallback by chroma, so you know what older displays will see, and it can display the P3 and Rec2020 gamuts.

A rotatable 3D model and graphs show where a color sits in the space. It suits front-end developers moving a project's CSS colors to OKLCH or working with wide-gamut displays. The source is published on GitHub.
