#BBBBB6

sRGB: 187 / 187 / 182

Ancient mountains rise against oblivion
Restless constellations shimmer across boundless heavens
Eternal flames find forgotten pathways

#BBBBB6 belongs to the yellow family. Its hex code tells a screen to mix 187 red, 187 green and 182 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 60.0° lands in the yellow region. Its 3.5% saturation makes it close to gray at this lightness. HSL lightness is 72.4% 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 (10.90:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #BBBBB6 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: 10.90:1

Normal text: AAA
Large text: AAA

White text: 1.93:1

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

#B6B6BB sits half a turn (180°) from #BBBBB6 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.

#BBBBB6 #B6B6BB

Analogous

#BBB9B6 and #B9BBB6 sit 30° to either side of #BBBBB6. 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.

#BBB9B6 #BBBBB6 #B9BBB6

Triadic

#BBBBB6, #B6BBBB and #BBB6BB are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#BBBBB6 #B6BBBB #BBB6BB

Split complementary

Start at #BBBBB6 and look across the wheel. #B6B9BB and #B9B6BB sit 30° to either side of its exact opposite, giving you two different accent choices.

#BBBBB6 #B6B9BB #B9B6BB

Square

Starting with #BBBBB6, each quarter turn (90°) takes you to the next hue: #B6BBB9, #B6B6BB, then #BBB6B9. Across the square, #BBBBB6 pairs with #B6B6BB, and #B6BBB9 with #BBB6B9.

#BBBBB6 #B6BBB9 #B6B6BB #BBB6B9

Tetradic

#BBBBB6 and #B6B6BB are opposites, as are #B6BBB6 and #BBB6BB. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #BBBBB6 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.

#BCBBB6

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.

#BCBBB6

Tritanopia

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

#BCBAB9

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.

#BCBBB6

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.

Tritanomaly (50%)

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