#FB91EF

sRGB · 251 / 145 / 239

#FB91EF belongs to the magenta family. Its hex code tells a screen to mix 251 red, 145 green and 239 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 306.8° lands in the magenta region. Its 93.0% saturation makes it strong in color at this lightness. HSL lightness is 77.6% 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 (10.40:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #FB91EF 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 · 10.40:1

Normal text: AAA
