#72EE21

sRGB · 114 / 238 / 33

#72EE21 belongs to the yellow-green family. Its hex code tells a screen to mix 114 red, 238 green and 33 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 96.3° lands in the yellow-green region. Its 85.8% saturation makes it strong in color at this lightness. HSL lightness is 53.1% 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 (13.97:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #72EE21 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 · 13.97:1

Normal text: AAA
