#D5FFFC belongs to the cyan family. Its hex code tells a screen to mix 213 red, 255 green and 252 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 175.7° lands in the cyan region. Its 100.0% saturation makes it strong in color at this lightness. HSL lightness is 91.8% 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 (19.54:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #D5FFFC 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: 19.54:1

Normal text: AAA
Large text: AAA

White text: 1.07:1

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

#FFD5D8 sits half a turn (180°) from #D5FFFC 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.

#D5FFFC #FFD5D8

Analogous

#D5FFE7 and #D5EDFF sit 30° to either side of #D5FFFC. 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.

#D5FFE7 #D5FFFC #D5EDFF

Triadic

#D5FFFC, #FCD5FF and #FFFCD5 are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#D5FFFC #FCD5FF #FFFCD5

Split complementary

Start at #D5FFFC and look across the wheel. #FFD5ED and #FFE7D5 sit 30° to either side of its exact opposite, giving you two different accent choices.

#D5FFFC #FFD5ED #FFE7D5

Square

Starting with #D5FFFC, each quarter turn (90°) takes you to the next hue: #E7D5FF, #FFD5D8, then #EDFFD5. Across the square, #D5FFFC pairs with #FFD5D8, and #E7D5FF with #EDFFD5.

#D5FFFC #E7D5FF #FFD5D8 #EDFFD5

Tetradic

#D5FFFC and #FFD5D8 are opposites, as are #D5D8FF and #FFFCD5. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #D5FFFC 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.

#FAFAFC

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.

#F1F4FD

Tritanopia

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

#C9FFFE

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.
