#AAA1CB belongs to the blue family. Its hex code tells a screen to mix 170 red, 161 green and 203 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 252.9° lands in the blue region. Its 28.8% saturation makes it close to gray at this lightness. HSL lightness is 71.4% 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 (8.67:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #AAA1CB 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: 8.67:1

Normal text: AAA
Large text: AAA

White text: 2.42:1

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

#C2CBA1 sits half a turn (180°) from #AAA1CB 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.

#AAA1CB #C2CBA1

Analogous

#A1ADCB and #BFA1CB sit 30° to either side of #AAA1CB. 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.

#A1ADCB #AAA1CB #BFA1CB

Triadic

#AAA1CB, #CBAAA1 and #A1CBAA are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#AAA1CB #CBAAA1 #A1CBAA

Split complementary

Start at #AAA1CB and look across the wheel. #CBBFA1 and #ADCBA1 sit 30° to either side of its exact opposite, giving you two different accent choices.

#AAA1CB #CBBFA1 #ADCBA1

Square

Starting with #AAA1CB, each quarter turn (90°) takes you to the next hue: #CBA1AD, #C2CBA1, then #A1CBBF. Across the square, #AAA1CB pairs with #C2CBA1, and #CBA1AD with #A1CBBF.

#AAA1CB #CBA1AD #C2CBA1 #A1CBBF

Tetradic

#AAA1CB and #C2CBA1 are opposites, as are #CBA1C2 and #A1CBAA. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #AAA1CB 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.

#99A6CA

Tritanopia

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

#A4A7AF

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.

#9EA5CC

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.

#9EA4CA

Tritanomaly (50%)

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