#F4FFDD

sRGB: 244 / 255 / 221

Cosmic tempests shimmer beneath moonlight
Unbridled forces transform the fabric of existence
Fierce revelations shatter the chains of fate

#F4FFDD belongs to the yellow-green family. Its hex code tells a screen to mix 244 red, 255 green and 221 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 79.4° lands in the yellow-green region. Its 100.0% saturation makes it strong in color at this lightness. HSL lightness is 93.3% 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 (20.19:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #F4FFDD 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: 20.19:1

Normal text: AAA
Large text: AAA

White text: 1.04:1

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

#E8DDFF sits half a turn (180°) from #F4FFDD 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.

#F4FFDD #E8DDFF

Analogous

#FFF9DD and #E3FFDD sit 30° to either side of #F4FFDD. 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.

#FFF9DD #F4FFDD #E3FFDD

Triadic

#F4FFDD, #DDF4FF and #FFDDF4 are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#F4FFDD #DDF4FF #FFDDF4

Split complementary

Start at #F4FFDD and look across the wheel. #DDE3FF and #F9DDFF sit 30° to either side of its exact opposite, giving you two different accent choices.

#F4FFDD #DDE3FF #F9DDFF

Square

Starting with #F4FFDD, each quarter turn (90°) takes you to the next hue: #DDFFF9, #E8DDFF, then #FFDDE3. Across the square, #F4FFDD pairs with #E8DDFF, and #DDFFF9 with #FFDDE3.

#F4FFDD #DDFFF9 #E8DDFF #FFDDE3

Tetradic

#F4FFDD and #E8DDFF are opposites, as are #DDFFE8 and #FFDDF4. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #F4FFDD 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.

#FFFBDB

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.

#FFFADE

Tritanopia

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