#00A004

sRGB · 0 / 160 / 4

#00A004 belongs to the green family. Its hex code tells a screen to mix 0 red, 160 green and 4 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 121.5° lands in the green region. Its 100.0% saturation makes it strong in color at this lightness. HSL lightness is 31.4% 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 (6.03:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #00A004 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 · 6.03:1

Normal text: AA
Large text: AAA

White text · 3.48:1

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. WCAG text contrast guidance

Complementary

#A0009C sits half a turn (180°) from #00A004 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.

#00A004 #A0009C

Analogous

#4CA000 and #00A054 sit 30° to either side of #00A004. 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.

#4CA000 #00A004 #00A054

Triadic

#00A004, #0400A0 and #A00400 are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.
