#59CD7C

sRGB: 89 / 205 / 124

#59CD7C belongs to the green-cyan family. Its hex code tells a screen to mix 89 red, 205 green and 124 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 138.1° lands in the green-cyan region. Its 53.7% saturation makes it partway between gray and the most vivid version of this hue at this lightness. HSL lightness is 57.6% 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 (10.45:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #59CD7C 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: 10.45:1

Normal text: AAA
Large text: AAA

White text: 2.01:1

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.
