#CEEDE4

sRGB: 206 / 237 / 228

Celestial flames fracture ancient heavens
Immortal legends illuminate forgotten empires
Infinite wonders drift toward tomorrow

#CEEDE4 belongs to the green-cyan family. Its hex code tells a screen to mix 206 red, 237 green and 228 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 162.6° lands in the green-cyan region. Its 46.3% saturation makes it partway between gray and the most vivid version of this hue at this lightness. HSL lightness is 86.9% 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 (16.86:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #CEEDE4 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: 16.86:1

Normal text: AAA
Large text: AAA

White text: 1.25:1

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

#EDCED7 sits half a turn (180°) from #CEEDE4 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.

#CEEDE4 #EDCED7

Analogous

#CEEDD5 and #CEE6ED sit 30° to either side of #CEEDE4. 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.

#CEEDD5 #CEEDE4 #CEE6ED

Triadic

#CEEDE4, #E4CEED and #EDE4CE are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#CEEDE4 #E4CEED #EDE4CE

Split complementary

Start at #CEEDE4 and look across the wheel. #EDCEE7 and #EDD5CE sit 30° to either side of its exact opposite, giving you two different accent choices.

#CEEDE4 #EDCEE7 #EDD5CE

Square

Starting with #CEEDE4, each quarter turn (90°) takes you to the next hue: #D5CEED, #EDCED7, then #E6EDCE. Across the square, #CEEDE4 pairs with #EDCED7, and #D5CEED with #E6EDCE.

#CEEDE4 #D5CEED #EDCED7 #E6EDCE

Tetradic

#CEEDE4 and #EDCED7 are opposites, as are #CED7ED and #EDE4CE. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Nearby colors

The nearest shorthand match is #CCEEDD. Its matching digit pairs let you write it as #CED in CSS. For a modern design, keep #CEEDE4 when you want an exact match. Use its web-safe neighbor, #CCFFCC, when matching a legacy palette of 216 colors.

Color vision previews

Compare how #CEEDE4 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.

#EAE9E4

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.

#E4E4E5

Tritanopia

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

#C7EEEA

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.

#E1EAE4

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.

Tritanomaly (50%)

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

#CEEDE6

Grayscale (luminance)

This design check removes hue and preserves relative luminance so you can compare light and dark areas.

#E6E6E6

Partial grayscale (50% blend)

This design check mixes the original color halfway toward its grayscale equivalent in linear light. Use it to see how a design holds up as color fades.
