#EADE21

sRGB: 234 / 222 / 33

Infinite horizons flourish beyond boundaries
Electric visions transcend the boundaries of time
Distant echoes surrender to silence

#EADE21 belongs to the yellow family. Its hex code tells a screen to mix 234 red, 222 green and 33 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 56.4° lands in the yellow region. Its 82.7% saturation makes it strong in color at this lightness. HSL lightness is 52.4% 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 (14.97:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #EADE21 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: 14.97:1

Normal text: AAA
Large text: AAA

White text: 1.40:1

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

#212DEA sits half a turn (180°) from #EADE21 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.

#EADE21 #212DEA

Analogous

#EA7921 and #92EA21 sit 30° to either side of #EADE21. 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.

#EA7921 #EADE21 #92EA21

Triadic

#EADE21, #21EADE and #DE21EA are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#EADE21 #21EADE #DE21EA

Split complementary

Start at #EADE21 and look across the wheel. #2192EA and #7921EA sit 30° to either side of its exact opposite, giving you two different accent choices.

#EADE21 #2192EA #7921EA

Square

Starting with #EADE21, each quarter turn (90°) takes you to the next hue: #21EA79, #212DEA, then #EA2192. Across the square, #EADE21 pairs with #212DEA, and #21EA79 with #EA2192.

#EADE21 #21EA79 #212DEA #EA2192

Tetradic

#EADE21 and #212DEA are opposites, as are #2DEA21 and #DE21EA. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #EADE21 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.

#F7DD36

Tritanopia

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

#FCCEBE

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.

#F0D900
