#DF00A9

sRGB: 223 / 0 / 169

#DF00A9 belongs to the magenta family. Its hex code tells a screen to mix 223 red, 0 green and 169 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 314.5° lands in the magenta region. Its 100.0% saturation makes it strong in color at this lightness. HSL lightness is 43.7% on a scale from black (0%) to white (100%). Of black and white lettering, black has the clearer light-to-dark separation on this background (4.71:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #DF00A9 in light and dark. The ratio compares relative luminance, a measure of light weighted for human vision. Identical colors give 1:1 and black against white gives 21:1. A ratio of 2.99:1 falls just below the 3:1 AA minimum for large text. Body text needs at least 4.5:1 because its finer strokes are harder to distinguish.

Black text: 4.71:1

Normal text: AA
Large text: AAA

White text: 4.46:1

Normal text: Fail
Large text: AA

AA and AAA are WCAG accessibility levels. AAA sets a higher bar: 7:1 for normal text and 4.5:1 for large text. Large text begins at 18 pt regular or 14 pt bold. Ratings use the unrounded ratio.

Harmonies rotate the hue. Scales mix the starting color with white, black or middle gray in 20% steps in encoded sRGB.

Complementary

#00DF36 sits half a turn (180°) from #DF00A9 on the HSL wheel. Keeping saturation and lightness steady while crossing to the opposite hue gives you a contrasting accent. Check text contrast separately before using the pair for lettering.

#DF00A9 #00DF36

Analogous

#A600DF and #DF0039 sit 30° to either side of #DF00A9. The three hues are neighbors on the wheel, so you can change the color of a border or highlight while keeping it close to the original.

#A600DF #DF00A9 #DF0039

Triadic

#DF00A9, #A9DF00 and #00A9DF are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.
