#FFFDFD

sRGB: 255 / 253 / 253
Color name: Whitecap Snow

#FFFDFD belongs to the red family. Its hex code tells a screen to mix 255 red, 253 green and 253 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 0.0° lands in the red region. Its 100.0% saturation makes it strong in color at this lightness. HSL lightness is 99.6% 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 #FFFDFD 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

#FDFFFF sits half a turn (180°) from #FFFDFD 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.

#FFFDFD #FDFFFF

Analogous

#FFFDFE and #FFFEFD sit 30° to either side of #FFFDFD. 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.

#FFFDFE #FFFDFD #FFFEFD

Triadic

#FFFDFD, #FDFFFD and #FDFDFF are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#FFFDFD #FDFFFD #FDFDFF

Split complementary

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

#FFFDFD #FDFFFE #FDFEFF

Square

Starting with #FFFDFD, each quarter turn (90°) takes you to the next hue: #FEFFFD, #FDFFFF, then #FEFDFF. Across the square, #FFFDFD pairs with #FDFFFF, and #FEFFFD with #FEFDFF.

#FFFDFD #FEFFFD #FDFFFF #FEFDFF

Tetradic

#FFFDFD and #FDFFFF are opposites, as are #FFFFFD and #FDFDFF. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Shades

Mixing #FFFDFD with black in 20% steps produces this scale. The first mixture, #CCCACA, keeps 80% of the original. By #333333, the mixture is 80% black.

Tones

Mixing #FFFDFD with middle gray in 20% steps produces this scale. The first mixture, #E6E4E4, keeps 80% of the original. By #999999, the mixture is 80% middle gray.

Blue 99.2%

CMYK

A simple CMYK estimate for #FFFDFD is 0.0% cyan, 0.8% magenta, 0.8% yellow and 0.0% black. These are ink amounts; a printer profile is needed to predict the result on paper.

Nearby colors

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

#FDFDFD

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.

#FEFEFD

Tritanopia

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

#FFFDFD

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.

#FEFDFD

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.

Grayscale (luminance)

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