#CBFEFE

sRGB: 203 / 254 / 254

Celestial flames rise against oblivion
Unbridled forces transcend the boundaries of time
Celestial symphonies transcend the limits of dreams

#CBFEFE belongs to the cyan family. Its hex code tells a screen to mix 203 red, 254 green and 254 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 180.0° lands in the cyan region. Its 96.2% saturation makes it strong in color at this lightness. HSL lightness is 89.6% 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 (19.15:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #CBFEFE 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: 19.15:1

Normal text: AAA
Large text: AAA

White text: 1.10:1

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

#FECBCB sits half a turn (180°) from #CBFEFE 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.

#CBFEFE #FECBCB

Analogous

#CBFEE4 and #CBE4FE sit 30° to either side of #CBFEFE. 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.

#CBFEE4 #CBFEFE #CBE4FE

Triadic

#CBFEFE, #FECBFE and #FEFECB are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#CBFEFE #FECBFE #FEFECB

Split complementary

Start at #CBFEFE and look across the wheel. #FECBE4 and #FEE4CB sit 30° to either side of its exact opposite, giving you two different accent choices.

#CBFEFE #FECBE4 #FEE4CB

Square

Starting with #CBFEFE, each quarter turn (90°) takes you to the next hue: #E4CBFE, #FECBCB, then #E4FECB. Across the square, #CBFEFE pairs with #FECBCB, and #E4CBFE with #E4FECB.

#CBFEFE #E4CBFE #FECBCB #E4FECB

Tetradic

#CBFEFE and #FECBCB are opposites, as are #CBCBFE and #FEFECB. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #CBFEFE 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.

#F7F9FE

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.

#EDF1FF

Tritanopia

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

#BBFFFE

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.

#E8FAFE

Deuteranomaly (50%)

#E4F6FE

Tritanomaly (50%)

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