#CFFFF0

sRGB: 207 / 255 / 240

Celestial flames reshape eternity
Unbridled forces transform the fabric of existence
Celestial symphonies vanish without farewell

#CFFFF0 belongs to the green-cyan family. Its hex code tells a screen to mix 207 red, 255 green and 240 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 161.2° lands in the green-cyan region. Its 100.0% saturation makes it strong in color at this lightness. HSL lightness is 90.6% 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 (19.22:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #CFFFF0 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: 19.22:1

Normal text: AAA
Large text: AAA

White text: 1.09:1

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

#FFCFDE sits half a turn (180°) from #CFFFF0 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.

#CFFFF0 #FFCFDE

Analogous

#CFFFD8 and #CFF6FF sit 30° to either side of #CFFFF0. 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.

#CFFFD8 #CFFFF0 #CFF6FF

Triadic

#CFFFF0, #F0CFFF and #FFF0CF are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#CFFFF0 #F0CFFF #FFF0CF

Split complementary

Start at #CFFFF0 and look across the wheel. #FFCFF6 and #FFD8CF sit 30° to either side of its exact opposite, giving you two different accent choices.

#CFFFF0 #FFCFF6 #FFD8CF

Square

Starting with #CFFFF0, each quarter turn (90°) takes you to the next hue: #D8CFFF, #FFCFDE, then #F6FFCF. Across the square, #CFFFF0 pairs with #FFCFDE, and #D8CFFF with #F6FFCF.

#CFFFF0 #D8CFFF #FFCFDE #F6FFCF

Tetradic

#CFFFF0 and #FFCFDE are opposites, as are #CFDEFF and #FFF0CF. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #CFFFF0 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.

Tritanopia

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

#C4FFFA
