#BBD7CF

sRGB: 187 / 215 / 207

Ancient mountains rise against oblivion
Electric visions unfold through ancient forests
Boundless spirits echo beyond eternity

#BBD7CF belongs to the green-cyan family. Its hex code tells a screen to mix 187 red, 215 green and 207 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 162.9° lands in the green-cyan region. Its 25.9% saturation makes it close to gray at this lightness. HSL lightness is 78.8% 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 (13.73:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #BBD7CF 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: 13.73:1

Normal text: AAA
Large text: AAA

White text: 1.53:1

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

#D7BBC3 sits half a turn (180°) from #BBD7CF 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.

#BBD7CF #D7BBC3

Analogous

#BBD7C1 and #BBD1D7 sit 30° to either side of #BBD7CF. 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.

#BBD7C1 #BBD7CF #BBD1D7

Triadic

#BBD7CF, #CFBBD7 and #D7CFBB are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#BBD7CF #CFBBD7 #D7CFBB

Split complementary

Start at #BBD7CF and look across the wheel. #D7BBD1 and #D7C1BB sit 30° to either side of its exact opposite, giving you two different accent choices.

#BBD7CF #D7BBD1 #D7C1BB

Square

Starting with #BBD7CF, each quarter turn (90°) takes you to the next hue: #C1BBD7, #D7BBC3, then #D1D7BB. Across the square, #BBD7CF pairs with #D7BBC3, and #C1BBD7 with #D1D7BB.

#BBD7CF #C1BBD7 #D7BBC3 #D1D7BB

Tetradic

Color vision previews

Compare how #BBD7CF 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.

#D5D3CF

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.

#CFCFD0

Tritanopia

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

#B5D8D4

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.

#CCD4CF

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.

#CAD2CF

Tritanomaly (50%)

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

#BBD7D1

Grayscale (luminance)

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