#EBF310

sRGB · 235 / 243 / 16

#EBF310 belongs to the yellow family. Its hex code tells a screen to mix 235 red, 243 green and 16 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 90.4% saturation makes it strong in color at this lightness. HSL lightness is 50.8% 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 (17.36:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #EBF310 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.

Color vision previews

Compare how #EBF310 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.

#FFEC33

Tritanopia

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