#BBDED3

sRGB: 187 / 222 / 211

Ancient mountains rise against oblivion
Electric visions transcend the boundaries of time
Fierce revelations linger beyond yesterday

#BBDED3 belongs to the green-cyan family. Its hex code tells a screen to mix 187 red, 222 green and 211 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 161.1° lands in the green-cyan region. Its 34.7% saturation makes it partway between gray and the most vivid version of this hue at this lightness. HSL lightness is 80.2% 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 (14.50:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #BBDED3 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: 14.50:1

Normal text: AAA
Large text: AAA

White text: 1.45:1

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

#DEBBC6 sits half a turn (180°) from #BBDED3 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.

#BBDED3 #DEBBC6

Analogous

#BBDEC1 and #BBD8DE sit 30° to either side of #BBDED3. 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.

#BBDEC1 #BBDED3 #BBD8DE

Triadic

#BBDED3, #D3BBDE and #DED3BB are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#BBDED3 #D3BBDE #DED3BB

Split complementary

Start at #BBDED3 and look across the wheel. #DEBBD8 and #DEC1BB sit 30° to either side of its exact opposite, giving you two different accent choices.

#BBDED3 #DEBBD8 #DEC1BB

Square

Starting with #BBDED3, each quarter turn (90°) takes you to the next hue: #C1BBDE, #DEBBC6, then #D8DEBB. Across the square, #BBDED3 pairs with #DEBBC6, and #C1BBDE with #D8DEBB.

#BBDED3 #C1BBDE #DEBBC6 #D8DEBB

Tetradic

#BBDED3 and #DEBBC6 are opposites, as are #BBC6DE and #DED3BB. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #BBDED3 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.

#DBD9D3

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.

#D5D4D4

Tritanopia

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

#B3DFDB

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.

#D1DAD3

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.

#CED8D4

Tritanomaly (50%)

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

Grayscale (luminance)

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