Opacity chart: HEX alpha and HSLA

In 8-digit HEX the last two digits set opacity: FF is fully opaque, 80 is about 50%, 00 is fully transparent. The table shows the example color at every 5% step.

About HSLA and LCH

HSLA is HSL plus an alpha channel for opacity, written as hsla(11, 100%, 60%, 0.5). Alpha goes from 0 (fully transparent) to 1 (fully opaque), and modern CSS also accepts it inside hsl().

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().

How the conversion works

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

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

Is the HSLA to LCH 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.
