ContrastOptions

Options shared by relativeLuminance, contrastRatio, contrastAPCA, meetsAA and meetsAAA.

interfaceimport type { ContrastOptions } from '@pbroom/color-kit';metrics.ts:31
interface ContrastOptions {
  gamut?: GamutTarget;
  precision?: ContrastPrecision;
}

Properties

gamut?GamutTargetdefault 'srgb'
Display gamut the colors are shown in. Channels are clipped to this gamut before luminance is measured, so out-of-gamut colors are measured as the display would render them by clipping. Contrast regions with gamut: 'display-p3' use the same setting.
precision?ContrastPrecisiondefault 'exact'
Channel precision; see ContrastPrecision.
