#DEFF84

sRGB: 222 / 255 / 132

Thunderous oceans fracture ancient heavens
Unbridled forces transform the fabric of existence
Golden visions drift toward tomorrow

#DEFF84 belongs to the yellow-green family. Its hex code tells a screen to mix 222 red, 255 green and 132 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 76.1° lands in the yellow-green region. Its 100.0% saturation makes it strong in color at this lightness. HSL lightness is 75.9% 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 (18.74:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #DEFF84 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: 18.74:1

Normal text: AAA
Large text: AAA

White text: 1.12:1

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

#A584FF sits half a turn (180°) from #DEFF84 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.

#DEFF84 #A584FF

Analogous

#FFE384 and #A0FF84 sit 30° to either side of #DEFF84. 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.

#FFE384 #DEFF84 #A0FF84

Triadic

#DEFF84, #84DEFF and #FF84DE are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#DEFF84 #84DEFF #FF84DE

Split complementary

Start at #DEFF84 and look across the wheel. #84A1FF and #E384FF sit 30° to either side of its exact opposite, giving you two different accent choices.

#DEFF84 #84A1FF #E384FF

Square

Starting with #DEFF84, each quarter turn (90°) takes you to the next hue: #84FFE3, #A584FF, then #FF84A1. Across the square, #DEFF84 pairs with #A584FF, and #84FFE3 with #FF84A1.

#DEFF84 #84FFE3 #A584FF #FF84A1

Tetradic

Color vision previews

Compare how #DEFF84 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.

Tritanopia

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

#E7F4E3

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.
