#FFEB65

sRGB: 255 / 235 / 101

Cosmic tempests reshape eternity
Immortal legends shimmer across boundless heavens
Wandering dreams settle beneath starlight

#FFEB65 belongs to the yellow family. Its hex code tells a screen to mix 255 red, 235 green and 101 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 52.2° lands in the yellow region. Its 100.0% saturation makes it strong in color at this lightness. HSL lightness is 69.8% 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 (17.32:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #FFEB65 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: 17.32:1

Normal text: AAA
Large text: AAA

White text: 1.21:1

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

#6579FF sits half a turn (180°) from #FFEB65 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.

#FFEB65 #6579FF

Analogous

#FF9E65 and #C6FF65 sit 30° to either side of #FFEB65. 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.

#FF9E65 #FFEB65 #C6FF65

Triadic

#FFEB65, #65FFEB and #EB65FF are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#FFEB65 #65FFEB #EB65FF

Split complementary

Start at #FFEB65 and look across the wheel. #65C6FF and #9E65FF sit 30° to either side of its exact opposite, giving you two different accent choices.

#FFEB65 #65C6FF #9E65FF

Square

Starting with #FFEB65, each quarter turn (90°) takes you to the next hue: #65FF9E, #6579FF, then #FF65C6. Across the square, #FFEB65 pairs with #6579FF, and #65FF9E with #FF65C6.

#FFEB65 #65FF9E #6579FF #FF65C6

Tetradic

#FFEB65 and #6579FF are opposites, as are #79FF65 and #EB65FF. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #FFEB65 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.

#FFED6C

Tritanopia

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

#FFDCCE

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.

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.
