#FDFFFD

sRGB · 253 / 255 / 253

#FDFFFD belongs to the green family. Its hex code tells a screen to mix 253 red, 255 green and 253 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 120.0° lands in the green 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 (20.90:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #FDFFFD 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 · 20.90:1

Normal text: AAA
Large text: AAA

White text · 1.00:1

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. WCAG text contrast guidance

Palettes & scales

Harmonies rotate the hue. Scales mix the starting color with white, black or middle gray in 20% steps in encoded sRGB.

Complementary

#FFFDFF sits half a turn (180°) from #FDFFFD 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.

#FDFFFD #FFFDFF

Analogous

#FEFFFD and #FDFFFE sit 30° to either side of #FDFFFD. 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.

#FEFFFD #FDFFFD #FDFFFE

Triadic

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

#FDFFFD #FDFDFF #FFFDFD

Split complementary

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

#FDFFFD #FEFDFF #FFFDFE

Square

Starting with #FDFFFD, each quarter turn (90°) takes you to the next hue: #FDFEFF, #FFFDFF, then #FFFEFD. Across the square, #FDFFFD pairs with #FFFDFF, and #FDFEFF with #FFFEFD.

#FDFFFD #FDFEFF #FFFDFF #FFFEFD

Tetradic

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

Color vision previews

Compare how #FDFFFD 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.

#FFFFFD

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.

#FFFEFD

Tritanopia

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

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.

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.
