#DEDFF5

sRGB: 222 / 223 / 245

Thunderous oceans fracture ancient heavens
Electric visions transform the fabric of existence

#DEDFF5 belongs to the blue family. Its hex code tells a screen to mix 222 red, 223 green and 245 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 237.4° lands in the blue region. Its 53.5% saturation makes it partway between gray and the most vivid version of this hue at this lightness. HSL lightness is 91.6% 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 (15.98:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #DEDFF5 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: 15.98:1

Normal text: AAA
Large text: AAA

White text: 1.31:1

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

#F5F4DE sits half a turn (180°) from #DEDFF5 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.

#DEDFF5 #F5F4DE

Analogous

#DEEBF5 and #E9DEF5 sit 30° to either side of #DEDFF5. 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.

#DEEBF5 #DEDFF5 #E9DEF5

Triadic

#DEDFF5, #F5DEDF and #DFF5DE are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#DEDFF5 #F5DEDF #DFF5DE

Split complementary

Start at #DEDFF5 and look across the wheel. #F5E9DE and #EBF5DE sit 30° to either side of its exact opposite, giving you two different accent choices.

#DEDFF5 #F5E9DE #EBF5DE

Square

Starting with #DEDFF5, each quarter turn (90°) takes you to the next hue: #F5DEEB, #F5F4DE, then #DEF5E9. Across the square, #DEDFF5 pairs with #F5F4DE, and #F5DEEB with #DEF5E9.

#DEDFF5 #F5DEEB #F5F4DE #DEF5E9

Tetradic

#DEDFF5 and #F5F4DE are opposites, as are #F4DEF5 and #DFF5DE. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #DEDFF5 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.

#DAE1F6

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.

#D9E0F4

Tritanopia

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

#D9E3E6

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.

#DBE0F6

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.

#DDE0F0

Grayscale (luminance)

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

#E0E0E0

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.
