#28FA49

sRGB · 40 / 250 / 73

#28FA49 belongs to the green family. Its hex code tells a screen to mix 40 red, 250 green and 73 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 129.4° lands in the green region. Its 95.5% saturation makes it strong in color at this lightness. HSL lightness is 56.9% 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 (14.86:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #28FA49 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 · 14.86:1

Normal text: AAA
