#01ACDC

sRGB · 1 / 172 / 220

#01ACDC belongs to the cyan family. Its hex code tells a screen to mix 1 red, 172 green and 220 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 193.2° lands in the cyan region. Its 99.1% saturation makes it strong in color at this lightness. HSL lightness is 43.3% 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 (7.94:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #01ACDC 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 · 7.94:1

Normal 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

Palettes & scales

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

Complementary

#DC3101 sits half a turn (180°) from #01ACDC 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.

#01ACDC #DC3101

Analogous

#01DC9E and #013FDC sit 30° to either side of #01ACDC. 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.

#01DC9E #01ACDC #013FDC

Triadic

#01ACDC, #DC01AC and #ACDC01 are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.
