#ECDFD9

sRGB: 236 / 223 / 217

Infinite horizons pierce eternal darkness
Electric visions transform the fabric of existence
Fierce revelations reveal unspoken wonders

#ECDFD9 belongs to the orange family. Its hex code tells a screen to mix 236 red, 223 green and 217 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 18.9° lands in the orange region. Its 33.3% saturation makes it partway between gray and the most vivid version of this hue at this lightness. HSL lightness is 88.8% 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 (16.12:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #ECDFD9 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: 16.12:1

Normal text: AAA
Large text: AAA

White text: 1.30:1

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

#D9E6EC sits half a turn (180°) from #ECDFD9 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.

#ECDFD9 #D9E6EC

Analogous

#ECD9DC and #ECE9D9 sit 30° to either side of #ECDFD9. 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.

#ECD9DC #ECDFD9 #ECE9D9

Triadic

#ECDFD9, #D9ECDF and #DFD9EC are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#ECDFD9 #D9ECDF #DFD9EC

Split complementary

Start at #ECDFD9 and look across the wheel. #D9ECE9 and #D9DCEC sit 30° to either side of its exact opposite, giving you two different accent choices.

#ECDFD9 #D9ECE9 #D9DCEC

Square

Starting with #ECDFD9, each quarter turn (90°) takes you to the next hue: #DCECD9, #D9E6EC, then #E9D9EC. Across the square, #ECDFD9 pairs with #D9E6EC, and #DCECD9 with #E9D9EC.

#ECDFD9 #DCECD9 #D9E6EC #E9D9EC

Tetradic

#ECDFD9 and #D9E6EC are opposites, as are #E6ECD9 and #DFD9EC. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #ECDFD9 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.

#E2E0D9

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.

#E5E2D9

Tritanopia

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

#F0DDDD

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.

#E6E0D9

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.

#E7E1D9

Tritanomaly (50%)

An altered short-wavelength cone response can make blue harder to distinguish from green. This swatch shows the model’s halfway setting.

#ECDFDB

Grayscale (luminance)

This design check removes hue and preserves relative luminance so you can compare light and dark areas.
