#FFFBB8

sRGB: 255 / 251 / 184

Cosmic tempests reshape eternity
Unbridled forces shimmer across boundless heavens
Eternal flames carry promises of spring

#FFFBB8 belongs to the yellow family. Its hex code tells a screen to mix 255 red, 251 green and 184 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 56.6° lands in the yellow region. Its 100.0% saturation makes it strong in color at this lightness. HSL lightness is 86.1% 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 (19.74:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #FFFBB8 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: 19.74:1

Normal text: AAA
Large text: AAA

White text: 1.06:1

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

#B8BCFF sits half a turn (180°) from #FFFBB8 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.

#FFFBB8 #B8BCFF

Analogous

#FFD7B8 and #E0FFB8 sit 30° to either side of #FFFBB8. 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.

#FFD7B8 #FFFBB8 #E0FFB8

Triadic

#FFFBB8, #B8FFFB and #FBB8FF 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 #FFFBB8 and look across the wheel. #B8E0FF and #D7B8FF sit 30° to either side of its exact opposite, giving you two different accent choices.

#FFFBB8 #B8E0FF #D7B8FF

Square

Starting with #FFFBB8, each quarter turn (90°) takes you to the next hue: #B8FFD7, #B8BCFF, then #FFB8E0. Across the square, #FFFBB8 pairs with #B8BCFF, and #B8FFD7 with #FFB8E0.

#FFFBB8 #B8FFD7 #B8BCFF #FFB8E0

Tetradic

#FFFBB8 and #B8BCFF are opposites, as are #BCFFB8 and #FBB8FF. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #FFFBB8 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.

#FFF9BB

Tritanopia

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

#FFF2E9

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.
