#9CF310

sRGB · 156 / 243 / 16

#9CF310 belongs to the yellow-green family. Its hex code tells a screen to mix 156 red, 243 green and 16 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 83.0° lands in the yellow-green region. Its 90.4% saturation makes it strong in color at this lightness. HSL lightness is 50.8% 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 (15.24:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #9CF310 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.
