#CDDDFD

sRGB: 205 / 221 / 253

Celestial flames command forgotten kingdoms

Celestial symphonies shatter the chains of fate

#CDDDFD belongs to the azure family. Its hex code tells a screen to mix 205 red, 221 green and 253 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 220.0° lands in the azure region. Its 92.3% saturation makes it strong in color at this lightness. HSL lightness is 89.8% 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 (15.36:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #CDDDFD 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: 15.36:1

Normal text: AAA
Large text: AAA

White text: 1.37:1

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

#FDEDCD sits half a turn (180°) from #CDDDFD 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.

#CDDDFD #FDEDCD

Analogous

#CDF5FD and #D5CDFD sit 30° to either side of #CDDDFD. 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.

#CDF5FD #CDDDFD #D5CDFD

Triadic

#CDDDFD, #FDCDDD and #DDFDCD are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#CDDDFD #FDCDDD #DDFDCD

Split complementary

Start at #CDDDFD and look across the wheel. #FDD5CD and #F5FDCD sit 30° to either side of its exact opposite, giving you two different accent choices.

#CDDDFD #FDD5CD #F5FDCD

Square

Starting with #CDDDFD, each quarter turn (90°) takes you to the next hue: #FDCDF5, #FDEDCD, then #CDFDD5. Across the square, #CDDDFD pairs with #FDEDCD, and #FDCDF5 with #CDFDD5.

#CDDDFD #FDCDF5 #FDEDCD #CDFDD5

Tetradic

#CDDDFD and #FDEDCD are opposites, as are #EDCDFD and #DDFDCD. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Nearby colors

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

Color vision previews

Compare how #CDDDFD 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.

#D3DFFF

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.

#CFDAFC

Tritanopia

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

#C1E3E7

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.

#CFDCFD

Tritanomaly (50%)

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

#CBDFF5

Grayscale (luminance)

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