#AFD00A

sRGB: 175 / 208 / 10

Radiant blossoms reshape eternity
Electric visions fade beyond remembrance
Lost whispers illuminate hidden worlds

#AFD00A belongs to the yellow family. Its hex code tells a screen to mix 175 red, 208 green and 10 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 70.0° lands in the yellow region. Its 90.8% saturation makes it strong in color at this lightness. HSL lightness is 42.7% 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 (11.85:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #AFD00A 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: 11.85:1

Normal text: AAA
Large text: AAA

White text: 1.77:1

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

#2B0AD0 sits half a turn (180°) from #AFD00A 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.

#AFD00A #2B0AD0

Analogous

#D08E0A and #4CD00A sit 30° to either side of #AFD00A. 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.

#D08E0A #AFD00A #4CD00A

Triadic

#AFD00A, #0AAFD0 and #D00AAF are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#AFD00A #0AAFD0 #D00AAF

Split complementary

Start at #AFD00A and look across the wheel. #0A4CD0 and #8E0AD0 sit 30° to either side of its exact opposite, giving you two different accent choices.

#AFD00A #0A4CD0 #8E0AD0

Square

Starting with #AFD00A, each quarter turn (90°) takes you to the next hue: #0AD08E, #2B0AD0, then #D00A4C. Across the square, #AFD00A pairs with #2B0AD0, and #0AD08E with #D00A4C.

#AFD00A #0AD08E #2B0AD0 #D00A4C

Tetradic

#AFD00A and #2B0AD0 are opposites, as are #0AD02B and #D00AAF. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.
