#ADED81

sRGB · 173 / 237 / 129

#ADED81 belongs to the yellow-green family. Its hex code tells a screen to mix 173 red, 237 green and 129 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 95.6° lands in the yellow-green region. Its 75.0% saturation makes it strong in color at this lightness. HSL lightness is 71.8% 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 (15.21:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #ADED81 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.

Complementary

#C181ED sits half a turn (180°) from #ADED81 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.

#ADED81 #C181ED

Analogous

#E3ED81 and #81ED8B sit 30° to either side of #ADED81. 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.

#E3ED81 #ADED81 #81ED8B

Triadic

#ADED81, #81ADED and #ED81AD are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

Color vision previews

Compare how #ADED81 appears in each simulation. When two chart lines or status indicators become hard to tell apart, a label, shape or line pattern gives readers another way to distinguish them. Individual perception varies.

Protanopia

A red–green color vision deficiency. Without a distinct response from long-wavelength cones, some reds and greens can look alike, and reds can appear darker.
