## What it is
A web-based color picker and converter for the OKLCH and LCH color spaces, available at oklch.com. It helps designers and developers convert colors from HEX/RGB/HSL, visualize gamuts like P3 and Rec. 2020, and build accessible palettes.

## Use cases
- convert hex or hsl colors to oklch
- build an accessible color palette in oklch
- pick colors in p3 gamut for modern screens
- visualize oklch color space in 3d
- find closest srgb fallback for wide-gamut colors
- learn why oklch is better than rgb and hsl for css

## When to choose
- you are working with CSS oklch() colors and need to pick or convert values
- you are designing a color system with predictable contrast and accessibility
- you need to convert legacy hex/rgb/hsl palettes to OKLCH
- you target wide-gamut displays (P3, Rec. 2020)

## When to avoid
- you only need simple hex color picking with no color-space conversion
- you need a native desktop color picker rather than a web tool
- you need a programmatic color conversion library rather than an interactive tool
