#DEFEAD

sRGB: 222 / 254 / 173

Thunderous oceans fracture ancient heavens
Unbridled forces transcend the boundaries of time
Brilliant stars shatter the chains of fate

#DEFEAD belongs to the yellow-green family. Its hex code tells a screen to mix 222 red, 254 green and 173 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 83.7° lands in the yellow-green region. Its 97.6% saturation makes it strong in color at this lightness. HSL lightness is 83.7% 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 (18.89:1), 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 #DEFEAD 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: 18.89:1

Normal text: AAA
Large text: AAA

White text: 1.11:1

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

#CDADFE sits half a turn (180°) from #DEFEAD 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.

#DEFEAD #CDADFE

Analogous

#FEF5AD and #B6FEAD sit 30° to either side of #DEFEAD. 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.

#FEF5AD #DEFEAD #B6FEAD

Triadic

#DEFEAD, #ADDEFE and #FEADDE are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#DEFEAD #ADDEFE #FEADDE

Split complementary

Start at #DEFEAD and look across the wheel. #ADB6FE and #F6ADFE sit 30° to either side of its exact opposite, giving you two different accent choices.

#DEFEAD #ADB6FE #F6ADFE

Square

Starting with #DEFEAD, each quarter turn (90°) takes you to the next hue: #ADFEF6, #CDADFE, then #FEADB6. Across the square, #DEFEAD pairs with #CDADFE, and #ADFEF6 with #FEADB6.

#DEFEAD #ADFEF6 #CDADFE #FEADB6

Tetradic

#DEFEAD and #CDADFE are opposites, as are #ADFECD and #FEADDE. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #DEFEAD 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.

#FFF4A8

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.

#FFF2B1

Tritanopia

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

#E3F7E9

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.

An altered medium-wavelength cone response can reduce the visible difference between reds and greens. This swatch shows the model’s halfway setting.

#F8F6AF

Tritanomaly (50%)

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

#E1FBC6

Grayscale (luminance)

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

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.
