#05AB71

sRGB: 5 / 171 / 113

#05AB71 belongs to the green-cyan family. Its hex code tells a screen to mix 5 red, 171 green and 113 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 159.0° lands in the green-cyan region. Its 94.3% saturation makes it strong in color at this lightness. HSL lightness is 34.5% 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 (7.07:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #05AB71 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: 7.07:1

Normal text: AAA
Large text: AAA

White text: 2.97:1

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.
