#BBB3FD

sRGB: 187 / 179 / 253

Ancient mountains rise against oblivion
Restless constellations flicker through endless evenings
Celestial symphonies shatter the chains of fate

#BBB3FD belongs to the blue family. Its hex code tells a screen to mix 187 red, 179 green and 253 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 246.5° lands in the blue region. Its 94.9% saturation makes it strong in color at this lightness. HSL lightness is 84.7% 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 (10.98:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #BBB3FD 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: 10.98:1

Normal text: AAA
Large text: AAA

White text: 1.91:1

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

#F5FDB3 sits half a turn (180°) from #BBB3FD 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.

#BBB3FD #F5FDB3

Analogous

#B3D0FD and #E0B3FD sit 30° to either side of #BBB3FD. 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.

#B3D0FD #BBB3FD #E0B3FD

Triadic

#BBB3FD, #FDBBB3 and #B3FDBB 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 #BBB3FD and look across the wheel. #FDE0B3 and #D0FDB3 sit 30° to either side of its exact opposite, giving you two different accent choices.

#BBB3FD #FDE0B3 #D0FDB3

Square

Starting with #BBB3FD, each quarter turn (90°) takes you to the next hue: #FDB3D0, #F5FDB3, then #B3FDE0. Across the square, #BBB3FD pairs with #F5FDB3, and #FDB3D0 with #B3FDE0.

#BBB3FD #FDB3D0 #F5FDB3 #B3FDE0

Tetradic

#BBB3FD and #F5FDB3 are opposites, as are #FDB3F5 and #B3FDBB. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #BBB3FD 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.

#9FBDFF

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.

#9FBAFB

Tritanopia

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

#ACC0CD

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.

#A9B9FE

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.

#A8B8FC

Tritanomaly (50%)

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

#B7B7ED

Grayscale (luminance)

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

#BBBBBB

Partial grayscale (50% blend)

This design check mixes the original color halfway toward its grayscale equivalent in linear light. Use it to see how a design holds up as color fades.
