Use guidance

What this color may be suitable for

Not recommended

Normal-sized text

#AD7B7B does not reach 4.5:1 on white or Hue Codex paper, so it should not be used there for normal-sized text.

Potential fit

Controls and interface graphics

Against Hue Codex paper, the color reaches 3.41:1. That meets the 3:1 color-contrast threshold where WCAG 1.4.11 applies, but states, shape, and non-color cues still need review.

Readable pairing available

Colored surface or button fill

Black text provides the stronger black/white pairing on #AD7B7B at 5.9:1. This validates only that text pair, not hover, focus, disabled, or adjacent-color states.

Restrained neutral

Palette role

Its OKLCH chroma of 0.0627 is restrained, which is generally more suitable for surfaces, borders, or neutral system roles than for a vivid accent.

Pair available

Color used as foreground

The stronger black/white background is black at 5.9:1. Always retest against the actual rendered background and text size.

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.

Color relationships

Complementary, analogous, and triadic colors

Hue rotations use OKLCH while preserving lightness and requested chroma. When a rotated result falls outside sRGB, chroma is reduced deterministically and disclosed.

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.

Distance matching

Closest standardized and framework colors

Matches use straight-line OKLab distance ×100. A smaller value means the coordinates are closer in this model; it is not a claim that two tokens are interchangeable in a design system.
