#045331

sRGB · 4 / 83 / 49

#045331 belongs to the green-cyan family. Its hex code tells a screen to mix 4 red, 83 green and 49 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 154.2° lands in the green-cyan region. Its 90.8% saturation makes it strong in color at this lightness. HSL lightness is 17.1% 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 (9.18:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #045331 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 · 2.29:1

Normal text: Fail
