#59C19C

sRGB · 89 / 193 / 156

#59C19C belongs to the green-cyan family. Its hex code tells a screen to mix 89 red, 193 green and 156 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 158.7° lands in the green-cyan region. Its 45.6% saturation makes it partway between gray and the most vivid version of this hue at this lightness. HSL lightness is 55.3% 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 (9.53:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #59C19C 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 · 9.53:1

Normal text: AAA
