Normal state uses #FFEE22 with black text at 17.5:1.

Action

Primary button

Use the controls above or point to and press the button to inspect its visual states.

Status

Subtle alert badge

A 12% source tint over white provides the background; readable text is selected separately.

Ready for review

Form

Border and focus ring

Source ring on white: 1.2:1 · does not meet the 3:1 non-text threshold where applicable.

Surface

Card component

The selected state becomes the card surface with its strongest black-or-white text pairing.

Use guidance

What this color may be suitable for

Not recommended

Normal-sized text

#FFEE22 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 1.15:1. 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 #FFEE22 at 17.5:1. This validates only that text pair, not hover, focus, disabled, or adjacent-color states.

Distinctive accent

Palette role

Its OKLCH chroma of 0.1918 gives it enough visual presence for an accent or primary role when the tested foreground and neighboring colors pass.

Pair available

Color used as foreground

The stronger black/white background is black at 17.5:1. 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.

Complementary

Analogous

Analogous −30° Chroma fitted to sRGB
Analogous +30° Chroma fitted to sRGB

Triadic

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.
