Flutter / Compose to HEX examples
About Flutter / Compose and HEX
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.
HEX writes red, green and blue as two hexadecimal digits each, like #ff5733. It is the most common way to write colors on the web and in design tools.
How the conversion works
We read the Flutter / Compose value, convert it to CIE XYZ with the matrices from the CSS Color 4 specification and then into HEX. 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 Flutter / Compose to HEX?
Paste or type a Flutter / Compose value into the field above. PickShade converts it with the CSS Color 4 formulas as you type, and one click copies the HEX value.
Is the Flutter / Compose to HEX 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?
