#CBDEDE

sRGB: 203 / 222 / 222

Celestial flames rise against oblivion
Electric visions transcend the boundaries of time
Fierce revelations transcend the limits of dreams

#CBDEDE belongs to the cyan family. Its hex code tells a screen to mix 203 red, 222 green and 222 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 22.4% saturation makes it close to gray at this lightness. HSL lightness is 83.3% 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 (15.04:1), which helps the shapes of letters stand out.

CMYK uses a profile-free approximation. Printed output depends on the press, ink and paper. Lab uses a D65 white point.

Text contrast

Contrast tells you how clearly lettering separates from #CBDEDE 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: 15.04:1

Normal text: AAA
Large text: AAA

White text: 1.40:1

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

#DECBCB sits half a turn (180°) from #CBDEDE 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.

#CBDEDE #DECBCB

Analogous

#CBDED4 and #CBD4DE sit 30° to either side of #CBDEDE. 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.

#CBDED4 #CBDEDE #CBD4DE

Triadic

#CBDEDE, #DECBDE and #DEDECB are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#CBDEDE #DECBDE #DEDECB

Split complementary

Start at #CBDEDE and look across the wheel. #DECBD4 and #DED4CB sit 30° to either side of its exact opposite, giving you two different accent choices.

#CBDEDE #DECBD4 #DED4CB

Square

Starting with #CBDEDE, each quarter turn (90°) takes you to the next hue: #D4CBDE, #DECBCB, then #D4DECB. Across the square, #CBDEDE pairs with #DECBCB, and #D4CBDE with #D4DECB.

#CBDEDE #D4CBDE #DECBCB #D4DECB

Tetradic

#CBDEDE and #DECBCB are opposites, as are #CBCBDE and #DEDECB. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #CBDEDE 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.

#DBDCDE

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.

#D7D9DE

Tritanopia

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

#C6DFDE

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.

#D6DCDE

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.

#D4DBDE

Tritanomaly (50%)

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