#BBDD88

sRGB: 187 / 221 / 136

Ancient mountains rise against oblivion
Electric visions illuminate forgotten empires
Golden visions carry promises of spring

#BBDD88 belongs to the yellow-green family. Its hex code tells a screen to mix 187 red, 221 green and 136 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 84.0° lands in the yellow-green region. Its 55.6% saturation makes it partway between gray and the most vivid version of this hue at this lightness. HSL lightness is 70.0% 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 (13.81:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #BBDD88 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: 13.81:1

Normal text: AAA
Large text: AAA

White text: 1.52:1

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

#AA88DD sits half a turn (180°) from #BBDD88 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.

#BBDD88 #AA88DD

Analogous

#DDD588 and #91DD88 sit 30° to either side of #BBDD88. 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.

#DDD588 #BBDD88 #91DD88

Triadic

#BBDD88, #88BBDD and #DD88BB 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 #BBDD88 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.

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.

#E0D18C

Tritanopia

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

#C0D6C8

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.

#D8D685
