#EFF0EA

sRGB: 239 / 240 / 234

Infinite horizons reshape eternity
Unbridled forces fade beyond remembrance
Infinite wonders illuminate hidden worlds

#EFF0EA belongs to the yellow family. Its hex code tells a screen to mix 239 red, 240 green and 234 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 70.0° lands in the yellow region. Its 16.7% saturation makes it close to gray at this lightness. HSL lightness is 92.9% 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 (18.32:1), 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 #EFF0EA 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: 18.32:1

Normal text: AAA
Large text: AAA

White text: 1.15:1

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

#EBEAF0 sits half a turn (180°) from #EFF0EA 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.

#EFF0EA #EBEAF0

Analogous

#F0EEEA and #ECF0EA sit 30° to either side of #EFF0EA. 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.

#F0EEEA #EFF0EA #ECF0EA

Triadic

#EFF0EA, #EAEFF0 and #F0EAEF are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#EFF0EA #EAEFF0 #F0EAEF

Split complementary

Start at #EFF0EA and look across the wheel. #EAECF0 and #EEEAF0 sit 30° to either side of its exact opposite, giving you two different accent choices.

#EFF0EA #EAECF0 #EEEAF0

Square

Starting with #EFF0EA, each quarter turn (90°) takes you to the next hue: #EAF0EE, #EBEAF0, then #F0EAEC. Across the square, #EFF0EA pairs with #EBEAF0, and #EAF0EE with #F0EAEC.

#EFF0EA #EAF0EE #EBEAF0 #F0EAEC

Tetradic

#EFF0EA and #EBEAF0 are opposites, as are #EAF0EB and #F0EAEF. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Nearby colors

The nearest shorthand match is #EEEEEE. Its matching digit pairs let you write it as #EEE in CSS. For a modern design, keep #EFF0EA when you want an exact match. Use its web-safe neighbor, #FFFFFF, when matching a legacy palette of 216 colors.

Color vision previews

Compare how #EFF0EA 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.

#F1EFEA

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.

#F1EFEA

Tritanopia

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

#F0EFEE

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.

#F0F0EA

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

#F0F0EA

Tritanomaly (50%)

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

Grayscale (luminance)

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