#CEEBEC

sRGB: 206 / 235 / 236

Celestial flames fracture ancient heavens
Immortal legends shimmer across boundless heavens
Infinite wonders awaken sleeping galaxies

#CEEBEC belongs to the cyan family. Its hex code tells a screen to mix 206 red, 235 green and 236 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 182.0° lands in the cyan region. Its 44.1% saturation makes it partway between gray and the most vivid version of this hue at this lightness. HSL lightness is 86.7% 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 (16.72:1), which helps the shapes of letters stand out.

CMYK uses a profile-free approximation. Printed output depends on the press, ink and paper. Lab uses a D65 white point.

Text contrast

Contrast tells you how clearly lettering separates from #CEEBEC 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: 16.72:1

Normal text: AAA
Large text: AAA

White text: 1.26:1

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

#ECCFCE sits half a turn (180°) from #CEEBEC 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.

#CEEBEC #ECCFCE

Analogous

#CEECDE and #CEDCEC sit 30° to either side of #CEEBEC. 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.

#CEECDE #CEEBEC #CEDCEC

Triadic

#CEEBEC, #ECCEEB and #EBECCE are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#CEEBEC #ECCEEB #EBECCE

Split complementary

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

#CEEBEC #ECCEDC #ECDECE

Square

Starting with #CEEBEC, each quarter turn (90°) takes you to the next hue: #DECEEC, #ECCFCE, then #DCECCE. Across the square, #CEEBEC pairs with #ECCFCE, and #DECEEC with #DCECCE.

#CEEBEC #DECEEC #ECCFCE #DCECCE

Tetradic

#CEEBEC and #ECCFCE are opposites, as are #CFCEEC and #EBECCE. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Nearby colors

The nearest shorthand match is #CCEEEE. Its matching digit pairs let you write it as #CEE in CSS. For a modern design, keep #CEEBEC when you want an exact match. Use its web-safe neighbor, #CCFFFF, when matching a legacy palette of 216 colors.

Color vision previews

Compare how #CEEBEC 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.

#E7E8EC

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.

#E1E3EC

Tritanopia

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

#C5EDEB

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.

#DEE9EC

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.
