#AE030D

sRGB · 174 / 3 / 13

#AE030D belongs to the red family. Its hex code tells a screen to mix 174 red, 3 green and 13 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 356.5° lands in the red region. Its 96.6% saturation makes it strong in color at this lightness. HSL lightness is 34.7% 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 (7.45:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #AE030D 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 · 2.82:1

Normal text: Fail
Large text: Fail

White text · 7.45:1

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

Harmonies rotate the hue. Scales mix the starting color with white, black or middle gray in 20% steps in encoded sRGB.

Complementary

#03AEA4 sits half a turn (180°) from #AE030D on the HSL wheel. Keeping saturation and lightness steady while crossing to the opposite hue gives you a contrasting accent. Check text contrast separately before using the pair for lettering.

#AE030D #03AEA4

Analogous

#AE0362 and #AE4F03 sit 30° to either side of #AE030D. The three hues are neighbors on the wheel, so you can change the color of a border or highlight while keeping it close to the original.

#AE0362 #AE030D #AE4F03

Triadic

#AE030D, #0DAE03 and #030DAE are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.
