#BBFFBB

sRGB: 187 / 255 / 187

Ancient mountains rise against oblivion
Unbridled forces transform the fabric of existence
Eternal flames defy the passing ages

#BBFFBB belongs to the green family. Its hex code tells a screen to mix 187 red, 255 green and 187 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 120.0° lands in the green region. Its 100.0% saturation makes it strong in color at this lightness. HSL lightness is 86.7% 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 (18.13:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #BBFFBB 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: 18.13:1

Normal text: AAA
Large text: AAA

White text: 1.16:1

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

#FFBBFF sits half a turn (180°) from #BBFFBB 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.

#BBFFBB #FFBBFF

Analogous

#DDFFBB and #BBFFDD sit 30° to either side of #BBFFBB. 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.

#DDFFBB #BBFFBB #BBFFDD

Triadic

#BBFFBB, #BBBBFF and #FFBBBB are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#BBFFBB #BBBBFF #FFBBBB

Split complementary

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

#BBFFBB #DDBBFF #FFBBDD

Square

Starting with #BBFFBB, each quarter turn (90°) takes you to the next hue: #BBDDFF, #FFBBFF, then #FFDDBB. Across the square, #BBFFBB pairs with #FFBBFF, and #BBDDFF with #FFDDBB.

#BBFFBB #BBDDFF #FFBBFF #FFDDBB

Tetradic

#BBFFBB and #FFBBFF are opposites, as are #BBFFFF and #FFBBBB. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #BBFFBB 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.

#FFF3B7

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.

#F7ECBF

Tritanopia

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

#B4FBED

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.

#BDFDCF

Grayscale (luminance)

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