About OKLCH and RGBA

OKLCH is OKLab in polar form: lightness, chroma and hue. Tailwind CSS v4 uses it for its whole palette because changing lightness keeps the hue stable.

RGBA is RGB plus an alpha channel for opacity, written as rgba(255, 87, 51, 0.5). Alpha goes from 0 (fully transparent) to 1 (fully opaque). The same opacity can be written as 8-digit HEX, like #ff573380.

How the conversion works

We read the OKLCH value, convert it to CIE XYZ with the matrices from the CSS Color 4 specification and then into RGBA. 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 OKLCH to RGBA?

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

Is the OKLCH to RGBA 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.
