#DEEBF5

sRGB: 222 / 235 / 245

Thunderous oceans fracture ancient heavens
Immortal legends shimmer across boundless heavens
Celestial symphonies settle beneath starlight

#DEEBF5 belongs to the azure family. Its hex code tells a screen to mix 222 red, 235 green and 245 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 206.1° lands in the azure region. Its 53.5% saturation makes it partway between gray and the most vivid version of this hue at this lightness. HSL lightness is 91.6% 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 (17.31:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #DEEBF5 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: 17.31:1

Normal text: AAA
Large text: AAA

White text: 1.21:1

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

#F5E8DE sits half a turn (180°) from #DEEBF5 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.

#DEEBF5 #F5E8DE

Analogous

#DEF5F4 and #DEDFF5 sit 30° to either side of #DEEBF5. 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.

#DEF5F4 #DEEBF5 #DEDFF5

Triadic

#DEEBF5, #F5DEEB and #EBF5DE are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#DEEBF5 #F5DEEB #EBF5DE

Split complementary

Start at #DEEBF5 and look across the wheel. #F5DEDF and #F5F4DE sit 30° to either side of its exact opposite, giving you two different accent choices.

#DEEBF5 #F5DEDF #F5F4DE

Square

Starting with #DEEBF5, each quarter turn (90°) takes you to the next hue: #F4DEF5, #F5E8DE, then #DFF5DE. Across the square, #DEEBF5 pairs with #F5E8DE, and #F4DEF5 with #DFF5DE.

#DEEBF5 #F4DEF5 #F5E8DE #DFF5DE

Tetradic

#DEEBF5 and #F5E8DE are opposites, as are #E8DEF5 and #EBF5DE. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #DEEBF5 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.

#E7EBF6

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.

#E4E8F5

Tritanopia

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

#D8EDEE

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.

#E4EAF5

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.

#E2E9F5

Tritanomaly (50%)

An altered short-wavelength cone response can make blue harder to distinguish from green. This swatch shows the model’s halfway setting.
