#DADADD

sRGB: 218 / 218 / 221

Thunderous oceans flourish beyond boundaries
Electric visions awaken beneath celestial skies
Fierce revelations shatter the chains of fate

#DADADD belongs to the blue family. Its hex code tells a screen to mix 218 red, 218 green and 221 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 240.0° lands in the blue region. Its 4.2% saturation makes it close to gray at this lightness. HSL lightness is 86.1% 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 (15.05:1), which helps the shapes of letters stand out.

CMYK uses a profile-free approximation. Printed output depends on the press, ink and paper. Lab uses a D65 white point.

Text contrast

Contrast tells you how clearly lettering separates from #DADADD 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: 15.05:1

Normal text: AAA
Large text: AAA

White text: 1.40:1

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

#DDDDDA sits half a turn (180°) from #DADADD 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.

#DADADD #DDDDDA

Analogous

#DADCDD and #DCDADD sit 30° to either side of #DADADD. 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.

#DADCDD #DADADD #DCDADD

Triadic

#DADADD, #DDDADA and #DADDDA are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#DADADD #DDDADA #DADDDA

Split complementary

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

#DADADD #DDDCDA #DCDDDA

Square

Starting with #DADADD, each quarter turn (90°) takes you to the next hue: #DDDADC, #DDDDDA, then #DADDDC. Across the square, #DADADD pairs with #DDDDDA, and #DDDADC with #DADDDC.

#DADADD #DDDADC #DDDDDA #DADDDC

Tetradic

#DADADD and #DDDDDA are opposites, as are #DDDADD and #DADDDA. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

#DADADD #DDDADD #DDDDDA #DADDDA

Tints

Mixing #DADADD with white in 20% steps produces this scale. The first mixture, #E1E1E4, keeps 80% of the original. By #F8F8F8, the mixture is 80% white.

Shades

Mixing #DADADD with black in 20% steps produces this scale. The first mixture, #AEAEB1, keeps 80% of the original. By #2C2C2C, the mixture is 80% black.

#DADADD #AEAEB1 #838385 #575758 #2C2C2C #000000

Tones

Mixing #DADADD with middle gray in 20% steps produces this scale. The first mixture, #C8C8CA, keeps 80% of the original. By #929293, the mixture is 80% middle gray.

Blue 86.7%

CMYK

A simple CMYK estimate for #DADADD is 1.4% cyan, 1.4% magenta, 0.0% yellow and 13.3% black. These are ink amounts; a printer profile is needed to predict the result on paper.

Cyan 1.4%

Magenta 1.4%

Nearby colors

The nearest shorthand match is #DDDDDD. Its matching digit pairs let you write it as #DDD in CSS. For a modern design, keep #DADADD when you want an exact match. Use its web-safe neighbor, #CCCCCC, when matching a legacy palette of 216 colors.

Color vision previews

Compare how #DADADD 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.

#D9DADD

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.

#D9DADD

Tritanopia

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

#D9DADB

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.

#DADADD

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.

#DADADD

Tritanomaly (50%)

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

#DADADC

Grayscale (luminance)

This design check removes hue and preserves relative luminance so you can compare light and dark areas.

#DADADA

Partial grayscale (50% blend)

This design check mixes the original color halfway toward its grayscale equivalent in linear light. Use it to see how a design holds up as color fades.
