#DEE2DF

sRGB: 222 / 226 / 223

Thunderous oceans fracture ancient heavens
Immortal legends tremble in empty gardens
Fierce revelations echo beyond eternity

#DEE2DF belongs to the green-cyan family. Its hex code tells a screen to mix 222 red, 226 green and 223 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 135.0° lands in the green-cyan region. Its 6.5% saturation makes it close to gray at this lightness. HSL lightness is 87.8% 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 (16.05:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #DEE2DF 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: 16.05:1

Normal text: AAA
Large text: AAA

White text: 1.31:1

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

#E2DEE1 sits half a turn (180°) from #DEE2DF 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.

#DEE2DF #E2DEE1

Analogous

#DFE2DE and #DEE2E1 sit 30° to either side of #DEE2DF. 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.

#DFE2DE #DEE2DF #DEE2E1

Triadic

#DEE2DF, #DFDEE2 and #E2DFDE are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#DEE2DF #DFDEE2 #E2DFDE

Split complementary

Start at #DEE2DF and look across the wheel. #E1DEE2 and #E2DEDF sit 30° to either side of its exact opposite, giving you two different accent choices.

#DEE2DF #E1DEE2 #E2DEDF

Square

Starting with #DEE2DF, each quarter turn (90°) takes you to the next hue: #DEDFE2, #E2DEE1, then #E2E1DE. Across the square, #DEE2DF pairs with #E2DEE1, and #DEDFE2 with #E2E1DE.

#DEE2DF #DEDFE2 #E2DEE1 #E2E1DE

Tetradic

#DEE2DF and #E2DEE1 are opposites, as are #DEE1E2 and #E2DFDE. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #DEE2DF 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.

#E2E1DF

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.

#E1E1DF

Tritanopia

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

#DEE2E1

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.

#E1E1DF

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.
