#CFFBB1

sRGB: 207 / 251 / 177

Celestial flames reshape eternity
Unbridled forces shimmer across boundless heavens
Eternal flames surrender to silence

#CFFBB1 belongs to the yellow-green family. Its hex code tells a screen to mix 207 red, 251 green and 177 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 95.7° lands in the yellow-green region. Its 90.2% saturation makes it strong in color 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 (18.09:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #CFFBB1 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: 18.09:1

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

#DDB1FB sits half a turn (180°) from #CFFBB1 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.

#CFFBB1 #DDB1FB

Analogous

#F4FBB1 and #B1FBB8 sit 30° to either side of #CFFBB1. 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.

#F4FBB1 #CFFBB1 #B1FBB8

Triadic

#CFFBB1, #B1CFFB and #FBB1CF 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 #CFFBB1 and look across the wheel. #B8B1FB and #FBB1F4 sit 30° to either side of its exact opposite, giving you two different accent choices.

#CFFBB1 #B8B1FB #FBB1F4

Square

Starting with #CFFBB1, each quarter turn (90°) takes you to the next hue: #B1F4FB, #DDB1FB, then #FBB8B1. Across the square, #CFFBB1 pairs with #DDB1FB, and #B1F4FB with #FBB8B1.

#CFFBB1 #B1F4FB #DDB1FB #FBB8B1

Tetradic

#CFFBB1 and #DDB1FB are opposites, as are #B1FBDD and #FBB1CF. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #CFFBB1 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.

#FFF0AC

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.

#FAEDB5

Tritanopia

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

#D0F5E8

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.

#F1F4AF
