Opacity chart: HEX alpha and RGBA

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 RGBA and SwiftUI

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.

SwiftUI describes a color with red, green and blue from 0 to 1, written as Color(red: 1, green: 0.341, blue: 0.2). Opacity is added with the opacity parameter.

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 SwiftUI. 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 SwiftUI?

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 SwiftUI value.

Is the RGBA to SwiftUI 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.
