#899ECE

sRGB: 137 / 158 / 206

Golden embers surge toward distant shores
Shimmering rivers transcend the boundaries of time
Boundless spirits transcend the limits of dreams

#899ECE belongs to the azure family. Its hex code tells a screen to mix 137 red, 158 green and 206 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 221.7° lands in the azure region. Its 41.3% saturation makes it partway between gray and the most vivid version of this hue at this lightness. HSL lightness is 67.3% 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 (7.85:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #899ECE 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: 7.85:1

Normal text: AAA
Large text: AAA

White text: 2.68:1

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.

Analogous

#89C0CE and #9789CE sit 30° to either side of #899ECE. 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.

#89C0CE #899ECE #9789CE

Triadic

#899ECE, #CE899E and #9ECE89 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 #899ECE 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.

#889BCD

Tritanopia

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

#75A8AE

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.
