#DECD28

sRGB: 222 / 205 / 40

Thunderous oceans fracture ancient heavens
Majestic waterfalls illuminate forgotten empires
Distant echoes carry promises of spring

#DECD28 belongs to the yellow family. Its hex code tells a screen to mix 222 red, 205 green and 40 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 54.4° lands in the yellow region. Its 73.4% saturation makes it strong in color at this lightness. HSL lightness is 51.4% 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 (12.87:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #DECD28 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: 12.87:1

Normal text: AAA
Large text: AAA

White text: 1.63:1

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

#2839DE sits half a turn (180°) from #DECD28 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.

#DECD28 #2839DE

Analogous

#DE7228 and #94DE28 sit 30° to either side of #DECD28. 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.

#DE7228 #DECD28 #94DE28

Triadic

#DECD28, #28DECD and #CD28DE are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#DECD28 #28DECD #CD28DE

Split complementary

Start at #DECD28 and look across the wheel. #2894DE and #7228DE sit 30° to either side of its exact opposite, giving you two different accent choices.

#DECD28 #2894DE #7228DE

Square

Starting with #DECD28, each quarter turn (90°) takes you to the next hue: #28DE72, #2839DE, then #DE2894. Across the square, #DECD28 pairs with #2839DE, and #28DE72 with #DE2894.

#DECD28 #28DE72 #2839DE #DE2894

Tetradic

#DECD28 and #2839DE are opposites, as are #39DE28 and #CD28DE. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #DECD28 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.

#EFBEB0

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.
