#FDFFEE

sRGB: 253 / 255 / 238

Cosmic tempests command forgotten kingdoms
Unbridled forces transform the fabric of existence
Infinite wonders transcend the limits of dreams

#FDFFEE belongs to the yellow family. Its hex code tells a screen to mix 253 red, 255 green and 238 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 67.1° lands in the yellow region. Its 100.0% saturation makes it strong in color at this lightness. HSL lightness is 96.7% 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 (20.72:1), 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 #FDFFEE 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: 20.72:1

Normal text: AAA
Large text: AAA

White text: 1.01:1

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

#F0EEFF sits half a turn (180°) from #FDFFEE 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.

#FDFFEE #F0EEFF

Analogous

#FFF9EE and #F5FFEE sit 30° to either side of #FDFFEE. 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.

#FFF9EE #FDFFEE #F5FFEE

Triadic

#FDFFEE, #EEFDFF and #FFEEFD are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#FDFFEE #EEFDFF #FFEEFD

Split complementary

Start at #FDFFEE and look across the wheel. #EEF5FF and #F8EEFF sit 30° to either side of its exact opposite, giving you two different accent choices.

#FDFFEE #EEF5FF #F8EEFF

Square

Starting with #FDFFEE, each quarter turn (90°) takes you to the next hue: #EEFFF9, #F0EEFF, then #FFEEF5. Across the square, #FDFFEE pairs with #F0EEFF, and #EEFFF9 with #FFEEF5.

#FDFFEE #EEFFF9 #F0EEFF #FFEEF5

Tetradic

#FDFFEE and #F0EEFF are opposites, as are #EEFFF0 and #FFEEFD. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Nearby colors

The nearest shorthand match is #FFFFEE. Its matching digit pairs let you write it as #FFE in CSS. For a modern design, keep #FDFFEE 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 #FDFFEE 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.

#FFFDED

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.

#FFFEEF

Tritanopia

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

#FFFDFA

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.

#FFFEEE

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.

#FFFEEE

Tritanomaly (50%)

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

#FEFEF2

Grayscale (luminance)

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

#FDFDFD

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.
