#ACCAEB

sRGB: 172 / 202 / 235

Radiant blossoms pierce eternal darkness
Majestic waterfalls awaken beneath celestial skies
Infinite wonders defy the passing ages

#ACCAEB belongs to the azure family. Its hex code tells a screen to mix 172 red, 202 green and 235 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 211.4° lands in the azure region. Its 61.2% saturation makes it partway between gray and the most vivid version of this hue at this lightness. HSL lightness is 79.8% 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 (12.40:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #ACCAEB 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: 12.40:1

Normal text: AAA
Large text: AAA

White text: 1.69:1

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.

Palettes & scales

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

Complementary

#EBCDAC sits half a turn (180°) from #ACCAEB 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.

#ACCAEB #EBCDAC

Analogous

#ACE9EB and #AEACEB sit 30° to either side of #ACCAEB. 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.

#ACE9EB #ACCAEB #AEACEB

Triadic

#ACCAEB, #EBACCA and #CAEBAC are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#ACCAEB #EBACCA #CAEBAC

Split complementary

Start at #ACCAEB and look across the wheel. #EBAEAC and #E9EBAC sit 30° to either side of its exact opposite, giving you two different accent choices.

#ACCAEB #EBAEAC #E9EBAC

Square

Starting with #ACCAEB, each quarter turn (90°) takes you to the next hue: #EBACEA, #EBCDAC, then #ACEBAE. Across the square, #ACCAEB pairs with #EBCDAC, and #EBACEA with #ACEBAE.

#ACCAEB #EBACEA #EBCDAC #ACEBAE

Tetradic

#ACCAEB and #EBCDAC are opposites, as are #CDACEB and #CAEBAC. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #ACCAEB 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.

#BECBED

Deuteranopia

A red–green color vision deficiency. Without a distinct response from medium-wavelength cones, some greens can be difficult to distinguish from reds or browns.

#B6C4EA

Tritanopia

A blue–yellow color vision deficiency. Without a distinct response from short-wavelength cones, blue can resemble green, and yellow can resemble pink.

#9AD1D5

Protanomaly (50%)

An altered long-wavelength cone response can make reds appear dimmer and harder to distinguish from greens. This swatch shows the model’s halfway setting.

Grayscale (luminance)

This design check removes hue and preserves relative luminance so you can compare light and dark areas.
