#BBC4BC

sRGB: 187 / 196 / 188

Ancient mountains rise against oblivion
Majestic waterfalls breathe beneath silver clouds
Eternal flames awaken sleeping galaxies

#BBC4BC belongs to the green family. Its hex code tells a screen to mix 187 red, 196 green and 188 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 126.7° lands in the green region. Its 7.1% saturation makes it close to gray at this lightness. HSL lightness is 75.1% 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 (11.74:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #BBC4BC 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: 11.74:1

Normal text: AAA
Large text: AAA

White text: 1.79:1

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.

Harmonies rotate the hue. Scales mix the starting color with white, black or middle gray in 20% steps in encoded sRGB.

Complementary

#C4BBC3 sits half a turn (180°) from #BBC4BC 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.

#BBC4BC #C4BBC3

Analogous

#BEC4BB and #BBC4C1 sit 30° to either side of #BBC4BC. 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.

#BEC4BB #BBC4BC #BBC4C1

Triadic

#BBC4BC, #BCBBC4 and #C4BCBB are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

Color vision previews

Compare how #BBC4BC 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.

#C4C2BC

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.

#C3C1BC

Tritanopia

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

#BAC4C2

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.

#C1C3BC

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.

#C0C2BC

Tritanomaly (50%)

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

#BBC4BE

Grayscale (luminance)

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