Use guidance

What this color may be suitable for

Not recommended

Normal-sized text

#8C9494 does not reach 4.5:1 on white or Hue Codex paper, so it should not be used there for normal-sized text.

Needs a boundary

Controls and interface graphics

Against Hue Codex paper, the color reaches only 2.96:1. Use a contrasting border or another non-color boundary for meaningful controls and graphics.

Readable pairing available

Colored surface or button fill

Black text provides the stronger black/white pairing on #8C9494 at 6.78:1. This validates only that text pair, not hover, focus, disabled, or adjacent-color states.

Restrained neutral

Palette role

Its OKLCH chroma of 0.0093 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 6.78:1. 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.

Hue relationships are not meaningful for this near-neutral color

Its OKLCH chroma is too low for hue rotation to produce a trustworthy complementary or triadic recommendation. Use the lightness scale or pair it with a deliberately selected accent instead.

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.
