#CDECD3

sRGB: 205 / 236 / 211

Celestial flames command forgotten kingdoms
Immortal legends thunder through timeless canyons
Fierce revelations linger beyond yesterday

#CDECD3 belongs to the green family. Its hex code tells a screen to mix 205 red, 236 green and 211 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 131.6° lands in the green region. Its 44.9% 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 (16.53:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #CDECD3 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: 16.53:1

Normal text: AAA
Large text: AAA

White text: 1.27:1

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

#ECCDE6 sits half a turn (180°) from #CDECD3 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.

#CDECD3 #ECCDE6

Analogous

#D7ECCD and #CDECE2 sit 30° to either side of #CDECD3. 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.

#D7ECCD #CDECD3 #CDECE2

Triadic

#CDECD3, #D3CDEC and #ECD3CD are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#CDECD3 #D3CDEC #ECD3CD

Split complementary

Start at #CDECD3 and look across the wheel. #E2CDEC and #ECCDD7 sit 30° to either side of its exact opposite, giving you two different accent choices.

#CDECD3 #E2CDEC #ECCDD7

Square

Starting with #CDECD3, each quarter turn (90°) takes you to the next hue: #CDD7EC, #ECCDE6, then #ECE2CD. Across the square, #CDECD3 pairs with #ECCDE6, and #CDD7EC with #ECE2CD.

#CDECD3 #CDD7EC #ECCDE6 #ECE2CD

Tetradic

#CDECD3 and #ECCDE6 are opposites, as are #CDE6EC and #ECD3CD. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #CDECD3 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.

#ECE6D2

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.

#E7E3D4

Tritanopia

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

#C9EBE5

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.

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.

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

#CEEBDA

Grayscale (luminance)

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