#72B310

sRGB · 114 / 179 / 16

#72B310 belongs to the yellow-green family. Its hex code tells a screen to mix 114 red, 179 green and 16 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 83.9° lands in the yellow-green region. Its 83.6% saturation makes it strong in color at this lightness. HSL lightness is 38.2% 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 (8.17:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #72B310 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 · 8.17:1

Normal text: AAA
Large text: AAA

White text · 2.57:1

Normal text: Fail
Large text: Fail

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. WCAG text contrast guidance
