#DDEA39

sRGB: 221 / 234 / 57

Thunderous oceans command forgotten kingdoms
Immortal legends awaken beneath celestial skies
Fleeting moments reveal unspoken wonders

#DDEA39 belongs to the yellow family. Its hex code tells a screen to mix 221 red, 234 green and 57 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 64.4° lands in the yellow region. Its 80.8% saturation makes it strong in color at this lightness. HSL lightness is 57.1% 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 (15.90:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #DDEA39 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: 15.90:1

Normal text: AAA
Large text: AAA

White text: 1.32:1

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.

Color vision previews

Compare how #DDEA39 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.

#FBDE02

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.

#FBE249

Tritanopia

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

#ECDCC9

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.

#F2E32A

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.

#F2E442

Tritanomaly (50%)

An altered short-wavelength cone response can make blue harder to distinguish from green. This swatch shows the model’s halfway setting.

#E1E586

Grayscale (luminance)

This design check removes hue and preserves relative luminance so you can compare light and dark areas.

#E0E0E0

Partial grayscale (50% blend)
