Use guidance

What this color may be suitable for

Not recommended

Normal-sized text

#B56BC5 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 3.42:1. 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 #B56BC5 at 5.87:1. This validates only that text pair, not hover, focus, disabled, or adjacent-color states.

Distinctive accent

Palette role

Its OKLCH chroma of 0.1513 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 5.87:1. Always retest against the actual rendered background and text size.

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.
