#F0FFFD

sRGB: 240 / 255 / 253

Cosmic tempests linger without sound

#F0FFFD belongs to the cyan family. Its hex code tells a screen to mix 240 red, 255 green and 253 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 172.0° lands in the cyan region. Its 100.0% saturation makes it strong in color at this lightness. HSL lightness is 97.1% 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 (20.43:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #F0FFFD 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: 20.43:1

Normal text: AAA
Large text: AAA

White text: 1.03:1

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

#FFF0F2 sits half a turn (180°) from #F0FFFD 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.

#F0FFFD #FFF0F2

Analogous

#F0FFF6 and #F0FAFF sit 30° to either side of #F0FFFD. 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.

#F0FFF6 #F0FFFD #F0FAFF

Triadic

#F0FFFD, #FDF0FF and #FFFDF0 are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#F0FFFD #FDF0FF #FFFDF0

Split complementary

Start at #F0FFFD and look across the wheel. #FFF0FA and #FFF6F0 sit 30° to either side of its exact opposite, giving you two different accent choices.

#F0FFFD #FFF0FA #FFF6F0

Square

Starting with #F0FFFD, each quarter turn (90°) takes you to the next hue: #F5F0FF, #FFF0F2, then #FAFFF0. Across the square, #F0FFFD pairs with #FFF0F2, and #F5F0FF with #FAFFF0.

#F0FFFD #F5F0FF #FFF0F2 #FAFFF0

Tetradic

#F0FFFD and #FFF0F2 are opposites, as are #F0F2FF and #FFFDF0. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #F0FFFD 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.

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.

#FAFBFD

Tritanopia

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

#ECFFFE
