#80DAEE

sRGB: 128 / 218 / 238

#80DAEE belongs to the cyan family. Its hex code tells a screen to mix 128 red, 218 green and 238 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 190.9° lands in the cyan region. Its 76.4% saturation makes it strong in color at this lightness. HSL lightness is 71.8% 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 (13.18:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #80DAEE 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: 13.18:1

Normal text: AAA
Large text: AAA

White text: 1.59:1

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

#EE9480 sits half a turn (180°) from #80DAEE 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.

#80DAEE #EE9480

Analogous

#80EECB and #80A3EE sit 30° to either side of #80DAEE. 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.

#80EECB #80DAEE #80A3EE

Triadic

#80DAEE, #EE80DA and #DAEE80 are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

Color vision previews

Compare how #80DAEE 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.

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.

#B9C7EE

Tritanopia

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

#48E2E0

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.
