#45EDE2

sRGB · 69 / 237 / 226

#45EDE2 belongs to the cyan family. Its hex code tells a screen to mix 69 red, 237 green and 226 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 176.1° lands in the cyan region. Its 82.4% saturation makes it strong in color at this lightness. HSL lightness is 60.0% 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 (14.46:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #45EDE2 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 · 14.46:1

Normal text: AAA
Large text: AAA

White text · 1.45:1

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. WCAG text contrast guidance

Analogous

#45ED8E and #45A4ED sit 30° to either side of #45EDE2. 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.

#45ED8E #45EDE2 #45A4ED

Triadic

#45EDE2, #E245ED and #EDE245 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 #45EDE2 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.
