#FFFA3F

sRGB: 255 / 250 / 63

Cosmic tempests reshape eternity
Unbridled forces awaken beneath celestial skies
Fleeting moments echo beyond eternity

#FFFA3F belongs to the yellow family. Its hex code tells a screen to mix 255 red, 250 green and 63 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 58.4° lands in the yellow region. Its 100.0% saturation makes it strong in color at this lightness. HSL lightness is 62.4% 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 (19.00:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #FFFA3F 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: 19.00:1

Normal text: AAA
Large text: AAA

White text: 1.11:1

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

#3F44FF sits half a turn (180°) from #FFFA3F 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.

#FFFA3F #3F44FF

Analogous

#FF9A3F and #A4FF3F sit 30° to either side of #FFFA3F. 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.

#FF9A3F #FFFA3F #A4FF3F

Triadic

#FFFA3F, #3FFFFA and #FA3FFF are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#FFFA3F #3FFFFA #FA3FFF

Split complementary

Start at #FFFA3F and look across the wheel. #3FA4FF and #9A3FFF sit 30° to either side of its exact opposite, giving you two different accent choices.

#FFFA3F #3FA4FF #9A3FFF

Square

Starting with #FFFA3F, each quarter turn (90°) takes you to the next hue: #3FFF9A, #3F44FF, then #FF3FA4. Across the square, #FFFA3F pairs with #3F44FF, and #3FFF9A with #FF3FA4.

#FFFA3F #3FFF9A #3F44FF #FF3FA4

Tetradic

#FFFA3F and #3F44FF are opposites, as are #44FF3F and #FA3FFF. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #FFFA3F 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.

#FFF008

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.

#FFF64F

Tritanopia

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