#B2CCBC

sRGB: 178 / 204 / 188

Ancient mountains drift beyond memory
Majestic waterfalls thunder through timeless canyons
Eternal flames awaken sleeping galaxies

#B2CCBC belongs to the green-cyan family. Its hex code tells a screen to mix 178 red, 204 green and 188 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 143.1° lands in the green-cyan region. Its 20.3% saturation makes it close to gray at this lightness. HSL lightness is 74.9% 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 (12.26:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #B2CCBC 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: 12.26:1

Normal text: AAA
Large text: AAA

White text: 1.71:1

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

#CCB2C2 sits half a turn (180°) from #B2CCBC 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.

#B2CCBC #CCB2C2

Analogous

#B5CCB2 and #B2CCC9 sit 30° to either side of #B2CCBC. 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.

#B5CCB2 #B2CCBC #B2CCC9

Triadic

#B2CCBC, #BCB2CC and #CCBCB2 are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

Split complementary

Start at #B2CCBC and look across the wheel. #C9B2CC and #CCB2B5 sit 30° to either side of its exact opposite, giving you two different accent choices.

#B2CCBC #C9B2CC #CCB2B5

Square

Starting with #B2CCBC, each quarter turn (90°) takes you to the next hue: #B2B5CC, #CCB2C2, then #CCC9B2. Across the square, #B2CCBC pairs with #CCB2C2, and #B2B5CC with #CCC9B2.

#B2CCBC #B2B5CC #CCB2C2 #CCC9B2

Tetradic

#B2CCBC and #CCB2C2 are opposites, as are #B2C2CC and #CCBCB2. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #B2CCBC 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.

#CBC8BB

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.

#C7C4BD

Tritanopia

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

#AECCC7

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.
