Use guidance

What this color may be suitable for

Not recommended

Normal-sized text

#19F7BD 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 1.33:1. 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 #19F7BD at 15.08:1. This validates only that text pair, not hover, focus, disabled, or adjacent-color states.

Distinctive accent

Palette role

Its OKLCH chroma of 0.1735 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 15.08:1. 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.
