Functions

fun ColorToken.contrastRatio(other: ColorToken): Double

WCAG 2.x contrast ratio between this token and other, from 1.0 (identical) to 21.0 (black on white). The result does not depend on argument order. Compare it with MIN_TEXT_CONTRAST or MIN_NON_TEXT_CONTRAST when validating a re-branded theme.

relativeLuminance

fun ColorToken.relativeLuminance(): Double

WCAG 2.x relative luminance in 0.0..1.0, computed from the sRGB channels. Alpha is ignored, so translucent tokens are measured as if they were opaque.
