#CFDBFE

sRGB: 207 / 219 / 254

Celestial flames reshape eternity
Electric visions shimmer across boundless heavens
Celestial symphonies transcend the limits of dreams

#CFDBFE belongs to the azure family. Its hex code tells a screen to mix 207 red, 219 green and 254 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 224.7° lands in the azure region. Its 95.9% saturation makes it strong in color at this lightness. HSL lightness is 90.4% 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 (15.22:1), which helps the shapes of letters stand out.

CMYK uses a profile-free approximation. Printed output depends on the press, ink and paper. Lab uses a D65 white point.

Text contrast

Contrast tells you how clearly lettering separates from #CFDBFE 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: 15.22:1

Normal text: AAA
Large text: AAA

White text: 1.38:1

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

#FEF2CF sits half a turn (180°) from #CFDBFE 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.

#CFDBFE #FEF2CF

Analogous

#CFF3FE and #DBCFFE sit 30° to either side of #CFDBFE. 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.

#CFF3FE #CFDBFE #DBCFFE

Triadic

#CFDBFE, #FECFDB and #DBFECF are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#CFDBFE #FECFDB #DBFECF

Split complementary

Start at #CFDBFE and look across the wheel. #FEDBCF and #F3FECF sit 30° to either side of its exact opposite, giving you two different accent choices.

#CFDBFE #FEDBCF #F3FECF

Square

Starting with #CFDBFE, each quarter turn (90°) takes you to the next hue: #FECFF3, #FEF2CF, then #CFFEDB. Across the square, #CFDBFE pairs with #FEF2CF, and #FECFF3 with #CFFEDB.

#CFDBFE #FECFF3 #FEF2CF #CFFEDB

Tetradic

#CFDBFE and #FEF2CF are opposites, as are #F2CFFE and #DBFECF. 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 #CFDBFE 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 #CFDBFE 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.

#D1DEFF

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.

#CDDAFD

Tritanopia

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

#C4E1E6

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.

#D0DCFF

#CDDDF6

Grayscale (luminance)

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