#3561BA

sRGB · 53 / 97 / 186

#3561BA belongs to the azure family. Its hex code tells a screen to mix 53 red, 97 green and 186 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 220.2° lands in the azure region. Its 55.6% saturation makes it partway between gray and the most vivid version of this hue at this lightness. HSL lightness is 46.9% on a scale from black (0%) to white (100%). Of black and white lettering, white has the clearer light-to-dark separation on this background (5.88:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #3561BA 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 · 3.57:1

Normal text: Fail
