#CED8EB

sRGB: 206 / 216 / 235

Celestial flames fracture ancient heavens
Electric visions echo between distant mountains
Infinite wonders defy the passing ages

#CED8EB belongs to the azure family. Its hex code tells a screen to mix 206 red, 216 green and 235 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 219.3° lands in the azure region. Its 42.0% saturation makes it partway between gray and the most vivid version of this hue at this lightness. HSL lightness is 86.5% 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 (14.65:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #CED8EB 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: 14.65:1

Normal text: AAA
Large text: AAA

White text: 1.43:1

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

#EBE1CE sits half a turn (180°) from #CED8EB 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.

#CED8EB #EBE1CE

Analogous

#CEE6EB and #D3CEEB sit 30° to either side of #CED8EB. 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.

#CEE6EB #CED8EB #D3CEEB

Triadic

#CED8EB, #EBCED8 and #D8EBCE are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#CED8EB #EBCED8 #D8EBCE

Split complementary

Start at #CED8EB and look across the wheel. #EBD3CE and #E6EBCE sit 30° to either side of its exact opposite, giving you two different accent choices.

#CED8EB #EBD3CE #E6EBCE

Square

Starting with #CED8EB, each quarter turn (90°) takes you to the next hue: #EBCEE6, #EBE1CE, then #CEEBD3. Across the square, #CED8EB pairs with #EBE1CE, and #EBCEE6 with #CEEBD3.

#CED8EB #EBCEE6 #EBE1CE #CEEBD3

Tetradic

#CED8EB and #EBE1CE are opposites, as are #E1CEEB and #D8EBCE. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #CED8EB 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.

#D2D9EC

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.

#D0D6EB

Tritanopia

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

#C7DCDE

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.
