#9EFCED

sRGB: 158 / 252 / 237

Restless currents fracture ancient heavens
Unbridled forces thunder through timeless canyons
Infinite wonders shatter the chains of fate

#9EFCED belongs to the cyan family. Its hex code tells a screen to mix 158 red, 252 green and 237 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 170.4° lands in the cyan region. Its 94.0% saturation makes it strong in color at this lightness. HSL lightness is 80.4% 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 (17.60:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #9EFCED 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: 17.60:1

Normal text: AAA
Large text: AAA

White text: 1.19:1

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

#FC9EAD sits half a turn (180°) from #9EFCED 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.

#9EFCED #FC9EAD

Analogous

#9EFCBE and #9EDCFC sit 30° to either side of #9EFCED. 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.

#9EFCBE #9EFCED #9EDCFC

Triadic

#9EFCED, #ED9EFC and #FCED9E are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#9EFCED #ED9EFC #FCED9E

Split complementary

Start at #9EFCED and look across the wheel. #FC9EDC and #FCBE9E sit 30° to either side of its exact opposite, giving you two different accent choices.

#9EFCED #FC9EDC #FCBE9E

Square

Starting with #9EFCED, each quarter turn (90°) takes you to the next hue: #BE9EFC, #FC9EAD, then #DCFC9E. Across the square, #9EFCED pairs with #FC9EAD, and #BE9EFC with #DCFC9E.

#9EFCED #BE9EFC #FC9EAD #DCFC9E

Tetradic

#9EFCED and #FC9EAD are opposites, as are #9EADFC and #FCED9E. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #9EFCED 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.

#E3E6EE

Tritanopia

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

#7CFFF7

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.
