#DFDF33

sRGB: 223 / 223 / 51

#DFDF33 belongs to the yellow family. Its hex code tells a screen to mix 223 red, 223 green and 51 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 72.9% saturation makes it strong in color at this lightness. HSL lightness is 53.7% 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 (14.74:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #DFDF33 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: 14.74:1

Normal text: AAA
Large text: AAA

White text: 1.42:1

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

#3333DF sits half a turn (180°) from #DFDF33 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.

#DFDF33 #3333DF

Analogous

#DF8933 and #89DF33 sit 30° to either side of #DFDF33. 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.

#DF8933 #DFDF33 #89DF33

Triadic

#DFDF33, #33DFDF and #DF33DF are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

Color vision previews

Compare how #DFDF33 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.

Tritanopia

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

#EFD0BF

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.

#ECD922

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.
