#DEEDFE

sRGB: 222 / 237 / 254

Thunderous oceans fracture ancient heavens
Immortal legends illuminate forgotten empires
Celestial symphonies transcend the limits of dreams

#DEEDFE belongs to the azure family. Its hex code tells a screen to mix 222 red, 237 green and 254 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 211.9° lands in the azure region. Its 94.1% saturation makes it strong in color at this lightness. HSL lightness is 93.3% 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 (17.65:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #DEEDFE 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: 17.65:1

Normal text: AAA
Large text: AAA

White text: 1.19:1

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

#FEEFDE sits half a turn (180°) from #DEEDFE 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.

#DEEDFE #FEEFDE

Analogous

#DEFDFE and #DFDEFE sit 30° to either side of #DEEDFE. 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.

#DEFDFE #DEEDFE #DFDEFE

Triadic

#DEEDFE, #FEDEED and #EDFEDE are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#DEEDFE #FEDEED #EDFEDE

Split complementary

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

#DEEDFE #FEDFDE #FDFEDE

Square

Starting with #DEEDFE, each quarter turn (90°) takes you to the next hue: #FEDEFD, #FEEFDE, then #DEFEDF. Across the square, #DEEDFE pairs with #FEEFDE, and #FEDEFD with #DEFEDF.

#DEEDFE #FEDEFD #FEEFDE #DEFEDF

Tetradic

#DEEDFE and #FEEFDE are opposites, as are #EFDEFE and #EDFEDE. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Nearby colors

The nearest shorthand match is #DDEEFF. Its matching digit pairs let you write it as #DEF in CSS. For a modern design, keep #DEEDFE 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 #DEEDFE 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.

#E7EDFF

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.

#E3EAFE

Tritanopia

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

#D6F1F2

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.

#E4EDFE

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.

#E2EBFE

Tritanomaly (50%)

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

#DDEEFA

Grayscale (luminance)

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

#EBEBEB

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.
