#AABCBE

sRGB: 170 / 188 / 190

Radiant blossoms flourish beyond boundaries
Restless constellations thunder through timeless canyons
Eternal flames transcend the limits of dreams

#AABCBE belongs to the cyan family. Its hex code tells a screen to mix 170 red, 188 green and 190 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 186.0° lands in the cyan region. Its 13.3% saturation makes it close to gray at this lightness. HSL lightness is 70.6% 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 (10.65:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #AABCBE 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: 10.65:1

Normal text: AAA
Large text: AAA

White text: 1.97:1

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

#BEACAA sits half a turn (180°) from #AABCBE 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.

#AABCBE #BEACAA

Analogous

#AABEB6 and #AAB2BE sit 30° to either side of #AABCBE. 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.

#AABEB6 #AABCBE #AAB2BE

Triadic

#AABCBE, #BEAABC and #BCBEAA are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#AABCBE #BEAABC #BCBEAA

Split complementary

Start at #AABCBE and look across the wheel. #BEAAB2 and #BEB6AA sit 30° to either side of its exact opposite, giving you two different accent choices.

#AABCBE #BEAAB2 #BEB6AA

Square

Starting with #AABCBE, each quarter turn (90°) takes you to the next hue: #B6AABE, #BEACAA, then #B2BEAA. Across the square, #AABCBE pairs with #BEACAA, and #B6AABE with #B2BEAA.

#AABCBE #B6AABE #BEACAA #B2BEAA

Tetradic

#AABCBE and #BEACAA are opposites, as are #ACAABE and #BCBEAA. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #AABCBE 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.

#B9BABE

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.

#B5B7BE

Tritanopia

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

#A5BEBD

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.

#B4BBBE

Deuteranomaly (50%)

An altered medium-wavelength cone response can reduce the visible difference between reds and greens. This swatch shows the model’s halfway setting.

#B2B9BE

Tritanomaly (50%)

An altered short-wavelength cone response can make blue harder to distinguish from green. 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.
