RGBA to HSL examples
About RGBA and HSL
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.
HSL describes hue in degrees, saturation and lightness in percent. It is easy to read, but its lightness is not perceptually even: yellow at 50% looks much lighter than blue at 50%.
How the conversion works
We read the RGBA value, convert it to CIE XYZ with the matrices from the CSS Color 4 specification and then into HSL. 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 RGBA to HSL?
Paste or type a RGBA value into the field above. PickShade converts it with the CSS Color 4 formulas as you type, and one click copies the HSL value.
Is the RGBA to HSL 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.
