About LCH and RGB

CIE LCH is Lab in polar form: lightness, chroma and hue. It is easier to reason about than Lab and is supported in CSS as lch().

RGB sets red, green and blue from 0 to 255. It describes how a screen mixes light and is written as rgb(255 87 51) in modern CSS.

How the conversion works

We read the LCH value, convert it to CIE XYZ with the matrices from the CSS Color 4 specification and then into RGB. Values outside the target gamut are mapped by the CSS Color 4 algorithm, which keeps lightness and hue and reduces chroma.

Questions and answers

How do I convert LCH to RGB?

Paste or type a LCH value into the field above. PickShade converts it with the CSS Color 4 formulas as you type, and one click copies the RGB value.

Is the LCH to RGB conversion exact?

The math is exact and the result is rounded only for display, with enough digits to convert back to the same color. If the color does not fit the target gamut, PickShade warns you and shows the nearest color that fits.

Can I get other formats at the same time?

Yes. Every other format, including OKLCH, Display P3, Tailwind, SwiftUI, Flutter and Android, is listed below the result and copies with one click.

Is this converter free?

Yes. It is free, needs no sign-up and runs entirely in your browser.
