Raxol.Terminal.Color.TrueColor.Conversion (Raxol Terminal v2.6.0)

Color space math for TrueColor: RGB/HSL/HSV/XYZ/Lab conversions and luminance calculations.

Summary

Converts HSL (h in 0..360, s/l in 0..1) to normalized RGB (0..1 each).

Converts HSV (h in 0..360, s/v in 0..1) to normalized RGB (0..1 each).

Calculates relative luminance for an 8-bit RGB color (WCAG formula).

Converts normalized RGB (0..1 each) to HSL tuple {h, s, l} where h is 0..360, s and l are 0..100.

Converts normalized RGB (0..1 each) to HSV tuple {h, s, v} where h is 0..360, s and v are 0..100.
