#FDFD98 belongs to the yellow family. Its hex code tells a screen to mix 253 red, 253 green and 152 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 60.0° lands in the yellow region. Its 96.2% saturation makes it strong in color at this lightness. HSL lightness is 79.4% 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 (19.68:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #FDFD98 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: 19.68:1

Normal text: AAA
Large text: AAA

White text: 1.07:1

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.

Color vision previews

Compare how #FDFD98 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.
