About HSL and Flutter / Compose

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%.

Flutter and Jetpack Compose write a color as one 32-bit ARGB number, like Color(0xFFFF5733). The two hex digits after 0x are the alpha, and FF means fully opaque.

How the conversion works

We read the HSL value, convert it to CIE XYZ with the matrices from the CSS Color 4 specification and then into Flutter / Compose. 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 HSL to Flutter / Compose?

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

Is the HSL to Flutter / Compose 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.
