#ECF080

sRGB · 236 / 240 / 128

#ECF080 belongs to the yellow family. Its hex code tells a screen to mix 236 red, 240 green and 128 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 62.1° lands in the yellow region. Its 78.9% saturation makes it strong in color at this lightness. HSL lightness is 72.2% 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 (17.34:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #ECF080 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.

Complementary

#8480F0 sits half a turn (180°) from #ECF080 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.

#ECF080 #8480F0

Analogous

#F0BC80 and #B4F080 sit 30° to either side of #ECF080. 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.

#F0BC80 #ECF080 #B4F080

Triadic

#ECF080, #80ECF0 and #F080EC are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.
