#FFF45D

sRGB: 255 / 244 / 93

Cosmic tempests reshape eternity
Unbridled forces breathe beneath silver clouds
Tender memories shatter the chains of fate

#FFF45D belongs to the yellow family. Its hex code tells a screen to mix 255 red, 244 green and 93 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 55.9° lands in the yellow region. Its 100.0% saturation makes it strong in color at this lightness. HSL lightness is 68.2% 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 (18.35:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #FFF45D 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: 18.35:1

Normal text: AAA
Large text: AAA

White text: 1.14:1

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

#5D68FF sits half a turn (180°) from #FFF45D 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.

#FFF45D #5D68FF

Analogous

#FFA35D and #B9FF5D sit 30° to either side of #FFF45D. 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.

#FFA35D #FFF45D #B9FF5D

Triadic

#FFF45D, #5DFFF4 and #F45DFF are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#FFF45D #5DFFF4 #F45DFF

Split complementary

Start at #FFF45D and look across the wheel. #5DB9FF and #A35DFF sit 30° to either side of its exact opposite, giving you two different accent choices.

#FFF45D #5DB9FF #A35DFF

Square

Starting with #FFF45D, each quarter turn (90°) takes you to the next hue: #5DFFA3, #5D68FF, then #FF5DB9. Across the square, #FFF45D pairs with #5D68FF, and #5DFFA3 with #FF5DB9.

#FFF45D #5DFFA3 #5D68FF #FF5DB9

Tetradic

#FFF45D and #5D68FF are opposites, as are #68FF5D and #F45DFF. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #FFF45D 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.

#FFF366

Tritanopia

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