Contrast against pure white and pure black
Pair this colour with the two extremes to see which is the safer text partner. AA needs 4.5:1 for body text and 3:1 for large text; AAA raises that to 7:1 and 4.5:1.
| Against | Hex | Ratio | AA text | AA large | AAA text |
|---|---|---|---|---|---|
| #FFFFFF | white | 2.07:1 | fail | fail | fail |
| #000000 | black | 10.15:1 | pass | pass | pass |
Tints and shades
Lightness moves in ten-point steps while hue and saturation stay fixed, which keeps the colour recognisable in a scale. The last column is the ratio against white text, useful for deciding where a scale stops working as a background.

Measured rather than eyeballed: hue 300.0°, saturation 47.3%, lightness 74.7%, relative luminance 0.4573 — four decimals is the precision the WCAG formula actually needs — and perceived brightness 72.6 out of 100. Entry 56 of 69 in this library, it scores 2.07:1 on white and 10.15:1 on black, a 8.08 spread. The complementary #a0dda0 sits 180° away on the wheel, and the scale brackets it with #a83ca8 below and #ffffff above.

Frequently asked questions
What text colour should sit on DDA0DD?
Black gives 10.15:1 and white gives 2.07:1, so black wins at 10.15:1. That clears the 4.5:1 AA threshold for normal text and the 7:1 AAA threshold as well.
Do the CMYK numbers match a print workflow?
They are the naive conversion from RGB, which assumes no ink limit, no colour profile and no black generation strategy. Real print work needs a profile-aware conversion; the values here are the ones the converter reports and are best used as a starting point for a designer rather than a press-ready separations file.
