#EFFCD8

sRGB: 239 / 252 / 216

Infinite horizons reshape eternity
Unbridled forces thunder through timeless canyons
Fierce revelations carry promises of spring

#EFFCD8 belongs to the yellow-green family. Its hex code tells a screen to mix 239 red, 252 green and 216 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 81.7° lands in the yellow-green region. Its 85.7% saturation makes it strong in color at this lightness. HSL lightness is 91.8% 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 (19.59:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #EFFCD8 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: 19.59:1

Normal text: AAA
Large text: AAA

White text: 1.07:1

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

#E5D8FC sits half a turn (180°) from #EFFCD8 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.

#EFFCD8 #E5D8FC

Analogous

#FCF7D8 and #DDFCD8 sit 30° to either side of #EFFCD8. 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.

#FCF7D8 #EFFCD8 #DDFCD8

Triadic

#EFFCD8, #D8EFFC and #FCD8EF are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#EFFCD8 #D8EFFC #FCD8EF

Split complementary

Start at #EFFCD8 and look across the wheel. #D8DDFC and #F7D8FC sit 30° to either side of its exact opposite, giving you two different accent choices.

#EFFCD8 #D8DDFC #F7D8FC

Square

Starting with #EFFCD8, each quarter turn (90°) takes you to the next hue: #D8FCF7, #E5D8FC, then #FCD8DD. Across the square, #EFFCD8 pairs with #E5D8FC, and #D8FCF7 with #FCD8DD.

#EFFCD8 #D8FCF7 #E5D8FC #FCD8DD

Tetradic

#EFFCD8 and #E5D8FC are opposites, as are #D8FCE5 and #FCD8EF. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #EFFCD8 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.

#FFF7D6

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.

#FFF7D9

Tritanopia

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

#F2F8F2

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.

#FBF9D7

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.

Tritanomaly (50%)

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

#F0FBE2

Grayscale (luminance)

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