#FE2221

sRGB: 254 / 34 / 33

#FE2221 belongs to the red family. Its hex code tells a screen to mix 254 red, 34 green and 33 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 0.3° lands in the red region. Its 99.1% saturation makes it strong in color at this lightness. HSL lightness is 56.3% 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 (5.46:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #FE2221 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: 5.46:1

Normal text: AA
Large text: AAA

White text: 3.84:1

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.

Analogous

#FE218F and #FE9021 sit 30° to either side of #FE2221. 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.

#FE218F #FE2221 #FE9021

Triadic

#FE2221, #21FE22 and #2221FE are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.
