#AAABCD

sRGB: 170 / 171 / 205

Radiant blossoms flourish beyond boundaries
Sacred blossoms shimmer across boundless heavens
Boundless spirits shatter the chains of fate

#AAABCD belongs to the blue family. Its hex code tells a screen to mix 170 red, 171 green and 205 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 238.3° lands in the blue region. Its 25.9% saturation makes it close to gray at this lightness. HSL lightness is 73.5% 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 (9.42:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #AAABCD 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: 9.42:1

Normal text: AAA
Large text: AAA

White text: 2.23:1

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

#CDCCAA sits half a turn (180°) from #AAABCD 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.

#AAABCD #CDCCAA

Analogous

#AABDCD and #BAAACD sit 30° to either side of #AAABCD. 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.

#AABDCD #AAABCD #BAAACD

Triadic

#AAABCD, #CDAAAB and #ABCDAA are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#AAABCD #CDAAAB #ABCDAA

Split complementary

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

#AAABCD #CDBAAA #BDCDAA

Square

Starting with #AAABCD, each quarter turn (90°) takes you to the next hue: #CDAABD, #CDCCAA, then #AACDBA. Across the square, #AAABCD pairs with #CDCCAA, and #CDAABD with #AACDBA.

#AAABCD #CDAABD #CDCCAA #AACDBA

Tetradic

#AAABCD and #CDCCAA are opposites, as are #CCAACD and #ABCDAA. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

#AAABCD #CCAACD #CDCCAA #ABCDAA

Color vision previews

Compare how #AAABCD 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.

#A3AFCF

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.

#A2ADCC

Tritanopia

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

#A3B1B6

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.

#A5ADCE
