#E6EB21

sRGB: 230 / 235 / 33

Infinite horizons emerge from slumber
Immortal legends shimmer across boundless heavens
Distant echoes surrender to silence

#E6EB21 belongs to the yellow family. Its hex code tells a screen to mix 230 red, 235 green and 33 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 61.5° lands in the yellow region. Its 83.5% saturation makes it strong in color at this lightness. HSL lightness is 52.5% 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 (16.27:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #E6EB21 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: 16.27:1

Normal text: AAA
Large text: AAA

White text: 1.29:1

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.

Analogous

#EB8B21 and #81EB21 sit 30° to either side of #E6EB21. 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.

#EB8B21 #E6EB21 #81EB21

Triadic

#E6EB21, #21E6EB and #EB21E6 are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

Color vision previews

Compare how #E6EB21 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.

#FFE539

Tritanopia

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

#F7DCC9

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.
