#CAAC21

sRGB: 202 / 172 / 33

Celestial flames flourish beyond boundaries
Sacred blossoms thunder through timeless canyons
Distant echoes surrender to silence

#CAAC21 belongs to the yellow family. Its hex code tells a screen to mix 202 red, 172 green and 33 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 49.3° lands in the yellow region. Its 71.9% saturation makes it strong in color at this lightness. HSL lightness is 46.1% 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 (9.43:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #CAAC21 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: 9.43:1

Normal text: AAA
Large text: AAA

White text: 2.23:1

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

#213FCA sits half a turn (180°) from #CAAC21 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.

#CAAC21 #213FCA

Analogous

#CA5821 and #94CA21 sit 30° to either side of #CAAC21. 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.

#CA5821 #CAAC21 #94CA21

Triadic

#CAAC21, #21CAAC and #AC21CA are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#CAAC21 #21CAAC #AC21CA

Split complementary

Start at #CAAC21 and look across the wheel. #2194CA and #5821CA sit 30° to either side of its exact opposite, giving you two different accent choices.

#CAAC21 #2194CA #5821CA

Square

Starting with #CAAC21, each quarter turn (90°) takes you to the next hue: #21CA58, #213FCA, then #CA2193. Across the square, #CAAC21 pairs with #213FCA, and #21CA58 with #CA2193.

#CAAC21 #21CA58 #213FCA #CA2193

Tetradic

#CAAC21 and #213FCA are opposites, as are #3FCA21 and #AC21CA. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #CAAC21 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.

#BFA800

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.

#C7B22C

Tritanopia

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

#DB9E93

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.

#C3AB0E

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.
