#F00A4F

sRGB: 240 / 10 / 79

Cosmic tempests linger without sound
Silent memories awaken beneath celestial skies

#F00A4F belongs to the rose family. Its hex code tells a screen to mix 240 red, 10 green and 79 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 342.0° lands in the rose region. Its 92.0% saturation makes it strong in color at this lightness. HSL lightness is 49.0% 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 (4.86:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #F00A4F 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: 4.86:1

Normal text: AA
Large text: AAA

White text: 4.32:1

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

#0AF0AB sits half a turn (180°) from #F00A4F 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.

#F00A4F #0AF0AB

Analogous

#F00AC2 and #F0380A sit 30° to either side of #F00A4F. 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.

#F00AC2 #F00A4F #F0380A

Triadic

#F00A4F, #4FF00A and #0A4FF0 are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.
