Thistle

Conversion

The same colour in each notation. OKLCH is the one to reach for when you intend to modify it, because its lightness axis is perceptually uniform and its three components are genuinely independent.

Contrast and accessibility

What this colour passes as text, and — where it fails — the nearest colour that would pass while holding the same hue.

APCA scores it Lc 30 as 16px regular text on white. That is below the threshold for body copy at that size, even where the WCAG ratio passes.

Using Thistle

In OKLCH terms this is a pink at 83% lightness and 0.04 chroma. Lightness is what decides every verdict below, which is why a colour can be perfect as a fill and unusable as the text on top of it.

• Body text on white1.69:1 is under the 4.5:1 minimum.no
• Body text on black12.36:1 clears the 4.5:1 minimum.yes
• Large text or headingsLarge text needs only 3:1, and this reaches 12.36:1 against black.yes
• Borders, icons and controlsClears the 3:1 that WCAG 1.4.11 asks of anything needed to identify a control.yes
• A background for white textWhite on this colour is 1.69:1.no

None of this makes a design accessible on its own. Contrast is one success criterion among many, and WCAG 1.4.1 separately requires that colour is never the only way information is conveyed — so if Thistle is carrying meaning here, give it a label or an icon as well.

Tints and shades

The same hue at eleven lightness steps, spaced evenly in OKLCH so they look evenly spaced. This is the family you would build a design system from.

Colour harmonies

Hue rotations around Thistle, computed in OKLCH so every colour in a set holds the same perceived lightness — which is what a harmony is supposed to mean and what the same rotation in HSL fails to deliver.
