#A30C19

sRGB · 163 / 12 / 25

#A30C19 belongs to the red family. Its hex code tells a screen to mix 163 red, 12 green and 25 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 354.8° lands in the red region. Its 86.3% saturation makes it strong in color at this lightness. HSL lightness is 34.3% 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 (8.00:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #A30C19 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 · 2.62:1

Normal text: Fail
Large text: Fail

White text · 8.00:1

Normal text: AAA
Large text: AAA

AA and AAA are WCAG accessibility levels. AAA sets a higher bar: 7:1 for normal text and 4.5:1 for large text. Large text begins at 18 pt regular or 14 pt bold. Ratings use the unrounded ratio. WCAG text contrast guidance
