#AABEEF

sRGB: 170 / 190 / 239

Radiant blossoms flourish beyond boundaries
Restless constellations transcend the boundaries of time
Infinite wonders echo beyond eternity

#AABEEF belongs to the azure family. Its hex code tells a screen to mix 170 red, 190 green and 239 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 222.6° lands in the azure region. Its 68.3% saturation makes it partway between gray and the most vivid version of this hue at this lightness. HSL lightness is 80.2% 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 (11.32:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #AABEEF 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: 11.32:1

Normal text: AAA
Large text: AAA

White text: 1.85:1

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

#EFDBAA sits half a turn (180°) from #AABEEF 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.

#AABEEF #EFDBAA

Analogous

#AAE1EF and #B8AAEF sit 30° to either side of #AABEEF. 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.

#AAE1EF #AABEEF #B8AAEF

Triadic

#AABEEF, #EFAABE and #BEEFAA are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#AABEEF #EFAABE #BEEFAA

Split complementary

Start at #AABEEF and look across the wheel. #EFB8AA and #E1EFAA sit 30° to either side of its exact opposite, giving you two different accent choices.

#AABEEF #EFB8AA #E1EFAA

Square

Starting with #AABEEF, each quarter turn (90°) takes you to the next hue: #EFAAE1, #EFDBAA, then #AAEFB8. Across the square, #AABEEF pairs with #EFDBAA, and #EFAAE1 with #AAEFB8.

#AABEEF #EFAAE1 #EFDBAA #AAEFB8

Tetradic

#AABEEF and #EFDBAA are opposites, as are #DBAAEF and #BEEFAA. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #AABEEF 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.

#AFC2F1

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.

#A8BBEE

Tritanopia

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

#97C8CE

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.
