#01ACDE

sRGB · 1 / 172 / 222

#01ACDE belongs to the cyan family. Its hex code tells a screen to mix 1 red, 172 green and 222 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 193.6° lands in the cyan region. Its 99.1% saturation makes it strong in color at this lightness. HSL lightness is 43.7% 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 (7.96:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #01ACDE 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 · 7.96:1

Normal text: AAA
Large text: AAA

White text · 2.64:1

Normal text: Fail
Large text: Fail

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

#DE3301 sits half a turn (180°) from #01ACDE 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.

#01ACDE #DE3301

Analogous

#01DEA2 and #013DDE sit 30° to either side of #01ACDE. 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.

#01DEA2 #01ACDE #013DDE

Triadic

#01ACDE, #DE01AC and #ACDE01 are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#01ACDE #DE01AC #ACDE01

Split complementary

Start at #01ACDE and look across the wheel. #DE013D and #DEA201 sit 30° to either side of its exact opposite, giving you two different accent choices.

#01ACDE #DE013D #DEA201

Square

Starting with #01ACDE, each quarter turn (90°) takes you to the next hue: #A201DE, #DE3301, then #3DDE01. Across the square, #01ACDE pairs with #DE3301, and #A201DE with #3DDE01.

#01ACDE #A201DE #DE3301 #3DDE01

Tetradic

#01ACDE and #DE3301 are opposites, as are #3301DE and #ACDE01. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #01ACDE appears in each simulation. When two chart lines or status indicators become hard to tell apart, a label, shape or line pattern gives readers another way to distinguish them. Individual perception varies.

Protanopia

A red–green color vision deficiency. Without a distinct response from long-wavelength cones, some reds and greens can look alike, and reds can appear darker.
