#BBCEFC

sRGB: 187 / 206 / 252

Ancient mountains rise against oblivion
Majestic waterfalls transcend the boundaries of time
Celestial symphonies awaken sleeping galaxies

#BBCEFC belongs to the azure family. Its hex code tells a screen to mix 187 red, 206 green and 252 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 222.5° lands in the azure region. Its 91.5% saturation makes it strong in color 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 (13.35:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #BBCEFC 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: 13.35:1

Normal text: AAA
Large text: AAA

White text: 1.57:1

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

#FCE9BB sits half a turn (180°) from #BBCEFC 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.

#BBCEFC #FCE9BB

Analogous

#BBEFFC and #C9BBFC sit 30° to either side of #BBCEFC. 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.

#BBEFFC #BBCEFC #C9BBFC

Triadic

#BBCEFC, #FCBBCE and #CEFCBB are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#BBCEFC #FCBBCE #CEFCBB

Split complementary

Start at #BBCEFC and look across the wheel. #FCC8BB and #EFFCBB sit 30° to either side of its exact opposite, giving you two different accent choices.

#BBCEFC #FCC8BB #EFFCBB

Square

Starting with #BBCEFC, each quarter turn (90°) takes you to the next hue: #FCBBEF, #FCE9BB, then #BBFCC8. Across the square, #BBCEFC pairs with #FCE9BB, and #FCBBEF with #BBFCC8.

#BBCEFC #FCBBEF #FCE9BB #BBFCC8

Tetradic

#BBCEFC and #FCE9BB are opposites, as are #E9BBFC and #CEFCBB. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #BBCEFC 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.

#C0D1FE

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.

#BACBFB

Tritanopia

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

#AAD7DD

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.

Tritanomaly (50%)

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

#B8D1F1

Grayscale (luminance)

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