#110022 reaches 19.19:1 on Hue Codex paper, meeting WCAG AA for normal text in that exact pairing.

Potential fit

Readable pairing available

Colored surface or button fill

Design-system starting point

A perceptual 50–900 reference scale

The source color is preserved at the nearest lightness step. Other swatches keep its OKLCH hue, moderate chroma toward the extremes, and reduce chroma only when needed to remain in sRGB.

Applied pairing

A small interface check

The source anchors the main action while the complement marks a secondary status. Contrast is selected separately for each fill.
