#AEFFFA

sRGB: 174 / 255 / 250

Radiant blossoms fracture ancient heavens

#AEFFFA belongs to the cyan family. Its hex code tells a screen to mix 174 red, 255 green and 250 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 176.3° lands in the cyan region. Its 100.0% saturation makes it strong in color at this lightness. HSL lightness is 84.1% 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 (18.48:1), 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 #AEFFFA 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: 18.48:1

Normal text: AAA
Large text: AAA

White text: 1.14:1

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

#FFAEB3 sits half a turn (180°) from #AEFFFA 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.

#AEFFFA #FFAEB3

Analogous

#AEFFD2 and #AEDBFF sit 30° to either side of #AEFFFA. 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.

#AEFFD2 #AEFFFA #AEDBFF

Triadic

#AEFFFA, #FAAEFF and #FFFAAE are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#AEFFFA #FAAEFF #FFFAAE

Split complementary

Start at #AEFFFA and look across the wheel. #FFAEDC and #FFD2AE sit 30° to either side of its exact opposite, giving you two different accent choices.

#AEFFFA #FFAEDC #FFD2AE

Square

Starting with #AEFFFA, each quarter turn (90°) takes you to the next hue: #D2AEFF, #FFAEB3, then #DBFFAE. Across the square, #AEFFFA pairs with #FFAEB3, and #D2AEFF with #DBFFAE.

#AEFFFA #D2AEFF #FFAEB3 #DBFFAE

Tetradic

#AEFFFA and #FFAEB3 are opposites, as are #AEB3FF and #FFFAAE. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #AEFFFA 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.

#F6F7FA

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.

#E7ECFB

Tritanopia

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

#91FFFD

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.

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.

#D9F3FB

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

#ADFFFB

Grayscale (luminance)

This design check removes hue and preserves relative luminance so you can compare light and dark areas.
