#DF5021

sRGB: 223 / 80 / 33

#DF5021 belongs to the red family. Its hex code tells a screen to mix 223 red, 80 green and 33 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 14.8° lands in the red region. Its 74.8% saturation makes it strong in color at this lightness. HSL lightness is 50.2% 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 (5.31:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #DF5021 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: 5.31:1

Normal text: AA
Large text: AAA

White text: 3.96:1

Normal text: Fail
Large text: AA

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.

Palettes & scales

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

Complementary

#21B0DF sits half a turn (180°) from #DF5021 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.

#DF5021 #21B0DF

Analogous

#DF2151 and #DFAF21 sit 30° to either side of #DF5021. 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.

#DF2151 #DF5021 #DFAF21

Triadic

#DF5021, #21DF50 and #5021DF are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.
