LCH Color Converter

How LCH Color Converter works

LCH Color Converter is designed to convert sRGB hex colors to CIE LCH and back. The path is sRGB to linear RGB, D65 XYZ, Lab, then cylindrical LCH, with hue measured by atan2. LCH Color Converter adds a focused result for this operation. For LCH Color Converter, its displayed result gives the current settings a concrete value that can be checked before anything is copied or downloaded.

With the default red hex value, the result is L 53.241, C 104.552, and H 39.999 degrees; converting those values back returns #ff0000. Use it to compare lightness and chroma independently when tuning a brand color or building a perceptually ordered ramp. In LCH Color Converter, that reproducible starting point makes later changes easier to evaluate because the underlying method stays constant.

Limits, output, and privacy

Very high chroma LCH values can describe colors that an sRGB monitor cannot reproduce, so the reverse result may clip. For LCH Color Converter, the conversion assumes standard sRGB and D65; colors outside the display gamut are clipped to available channel values. LCH Color Converter keeps the operation client-side. With LCH Color Converter, the page processes its source locally, then copies or downloads the in-memory result without uploading it.
