#D2EFDF

sRGB: 210 / 239 / 223

Thunderous oceans drift beyond memory
Immortal legends transform the fabric of existence
Fierce revelations echo beyond eternity

#D2EFDF belongs to the green-cyan family. Its hex code tells a screen to mix 210 red, 239 green and 223 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 146.9° lands in the green-cyan region. Its 47.5% saturation makes it partway between gray and the most vivid version of this hue at this lightness. HSL lightness is 88.0% 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 (17.15:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #D2EFDF 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: 17.15:1

Normal text: AAA
Large text: AAA

White text: 1.22:1

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

#EFD2E2 sits half a turn (180°) from #D2EFDF 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.

#D2EFDF #EFD2E2

Analogous

#D4EFD2 and #D2EFEE sit 30° to either side of #D2EFDF. 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.

#D4EFD2 #D2EFDF #D2EFEE

Triadic

#D2EFDF, #DFD2EF and #EFDFD2 are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#D2EFDF #DFD2EF #EFDFD2

Split complementary

Start at #D2EFDF and look across the wheel. #EED2EF and #EFD2D3 sit 30° to either side of its exact opposite, giving you two different accent choices.

#D2EFDF #EED2EF #EFD2D3

Square

Starting with #D2EFDF, each quarter turn (90°) takes you to the next hue: #D2D3EF, #EFD2E2, then #EFEDD2. Across the square, #D2EFDF pairs with #EFD2E2, and #D2D3EF with #EFEDD2.

#D2EFDF #D2D3EF #EFD2E2 #EFEDD2

Tetradic

#D2EFDF and #EFD2E2 are opposites, as are #D2E2EF and #EFDFD2. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #D2EFDF 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.
