#EFF1BB

sRGB: 239 / 241 / 187

Infinite horizons reshape eternity
Unbridled forces disappear beneath stillness
Eternal flames defy the passing ages

#EFF1BB belongs to the yellow family. Its hex code tells a screen to mix 239 red, 241 green and 187 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 62.2° lands in the yellow region. Its 65.9% saturation makes it partway between gray and the most vivid version of this hue at this lightness. HSL lightness is 83.9% 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 (17.97:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #EFF1BB 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: 17.97:1

Normal text: AAA
Large text: AAA

White text: 1.17:1

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

#BDBBF1 sits half a turn (180°) from #EFF1BB 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.

#EFF1BB #BDBBF1

Analogous

#F1D8BB and #D4F1BB sit 30° to either side of #EFF1BB. 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.

#F1D8BB #EFF1BB #D4F1BB

Triadic

#EFF1BB, #BBEFF1 and #F1BBEF are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#EFF1BB #BBEFF1 #F1BBEF

Split complementary

Start at #EFF1BB and look across the wheel. #BBD4F1 and #D8BBF1 sit 30° to either side of its exact opposite, giving you two different accent choices.

#EFF1BB #BBD4F1 #D8BBF1

Square

Starting with #EFF1BB, each quarter turn (90°) takes you to the next hue: #BBF1D8, #BDBBF1, then #F1BBD4. Across the square, #EFF1BB pairs with #BDBBF1, and #BBF1D8 with #F1BBD4.

#EFF1BB #BBF1D8 #BDBBF1 #F1BBD4

Tetradic

#EFF1BB and #BDBBF1 are opposites, as are #BBF1BD and #F1BBEF. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #EFF1BB 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.

#FAECB8

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.

#FBEEBD

Tritanopia

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

#F7EAE2

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.

#F6EEB9

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.

#F7EFBC

Tritanomaly (50%)

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

#F1EFCB

Grayscale (luminance)

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

#EDEDED

Partial grayscale (50% blend)
