#EFFFBA

sRGB: 239 / 255 / 186

Infinite horizons reshape eternity
Unbridled forces transform the fabric of existence
Eternal flames illuminate hidden worlds

#EFFFBA belongs to the yellow family. Its hex code tells a screen to mix 239 red, 255 green and 186 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 73.9° lands in the yellow region. Its 100.0% saturation makes it strong in color at this lightness. HSL lightness is 86.5% 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.

CMYK uses a profile-free approximation. Printed output depends on the press, ink and paper. Lab uses a D65 white point.

Text contrast

Contrast tells you how clearly lettering separates from #EFFFBA 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.

Palettes & scales

Harmonies rotate the hue. Scales mix the starting color with white, black or middle gray in 20% steps in encoded sRGB.

Complementary

#CABAFF sits half a turn (180°) from #EFFFBA 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.

#EFFFBA #CABAFF

Analogous

#FFEDBA and #CCFFBA sit 30° to either side of #EFFFBA. 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.

#FFEDBA #EFFFBA #CCFFBA

Triadic

#EFFFBA, #BAEFFF and #FFBAEF are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#EFFFBA #BAEFFF #FFBAEF

Split complementary

Start at #EFFFBA and look across the wheel. #BACCFF and #EDBAFF sit 30° to either side of its exact opposite, giving you two different accent choices.

#EFFFBA #BACCFF #EDBAFF

Square

Starting with #EFFFBA, each quarter turn (90°) takes you to the next hue: #BAFFED, #CABAFF, then #FFBACC. Across the square, #EFFFBA pairs with #CABAFF, and #BAFFED with #FFBACC.

#EFFFBA #BAFFED #CABAFF #FFBACC

Tetradic

#EFFFBA and #CABAFF are opposites, as are #BAFFCA and #FFBAEF. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

#EFFFBA #BAFFCA #CABAFF #FFBAEF

Tints

Mixing #EFFFBA with white in 20% steps produces this scale. The first mixture, #F2FFC8, keeps 80% of the original. By #FCFFF1, the mixture is 80% white.

Nearby colors

The nearest shorthand match is #EEFFBB. Its matching digit pairs let you write it as #EFB in CSS. For a modern design, keep #EFFFBA when you want an exact match. Use its web-safe neighbor, #FFFFCC, when matching a legacy palette of 216 colors.

Color vision previews

Compare how #EFFFBA 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.

#FFF7B6

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.

#FFF8BD

Tritanopia

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

#F6F8ED

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.
