#DDEBCC

sRGB: 221 / 235 / 204

Thunderous oceans command forgotten kingdoms
Immortal legends shimmer across boundless heavens
Boundless spirits awaken sleeping galaxies

#DDEBCC belongs to the yellow-green family. Its hex code tells a screen to mix 221 red, 235 green and 204 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 87.1° lands in the yellow-green region. Its 43.7% saturation makes it partway between gray and the most vivid version of this hue at this lightness. HSL lightness is 86.1% 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 (16.83:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #DDEBCC 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: 16.83:1

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

#DACCEB sits half a turn (180°) from #DDEBCC 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.

#DDEBCC #DACCEB

Analogous

#EBE9CC and #CEEBCC sit 30° to either side of #DDEBCC. 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.

#EBE9CC #DDEBCC #CEEBCC

Triadic

#DDEBCC, #CCDDEB and #EBCCDD are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#DDEBCC #CCDDEB #EBCCDD

Split complementary

Start at #DDEBCC and look across the wheel. #CCCEEB and #E9CCEB sit 30° to either side of its exact opposite, giving you two different accent choices.

#DDEBCC #CCCEEB #E9CCEB

Square

Starting with #DDEBCC, each quarter turn (90°) takes you to the next hue: #CCEBE9, #DACCEB, then #EBCCCE. Across the square, #DDEBCC pairs with #DACCEB, and #CCEBE9 with #EBCCCE.

#DDEBCC #CCEBE9 #DACCEB #EBCCCE

Tetradic

#DDEBCC and #DACCEB are opposites, as are #CCEBDA and #EBCCDD. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #DDEBCC 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.

#EFE7CA

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.

#EDE6CD

Tritanopia

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

#DFE8E2

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.
