#DCF2FF

sRGB: 220 / 242 / 255

Thunderous oceans pierce eternal darkness
Unbridled forces tremble in empty gardens
Celestial symphonies echo beyond eternity

#DCF2FF belongs to the azure family. Its hex code tells a screen to mix 220 red, 242 green and 255 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 202.3° lands in the azure region. Its 100.0% saturation makes it strong in color at this lightness. HSL lightness is 93.1% 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 (18.19:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #DCF2FF 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: 18.19:1

Normal text: AAA
Large text: AAA

White text: 1.15:1

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

#FFE9DC sits half a turn (180°) from #DCF2FF 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.

#DCF2FF #FFE9DC

Analogous

#DCFFFB and #DCE0FF sit 30° to either side of #DCF2FF. 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.

#DCFFFB #DCF2FF #DCE0FF

Triadic

#DCF2FF, #FFDCF2 and #F2FFDC are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#DCF2FF #FFDCF2 #F2FFDC

Split complementary

Start at #DCF2FF and look across the wheel. #FFDCE1 and #FFFBDC sit 30° to either side of its exact opposite, giving you two different accent choices.

#DCF2FF #FFDCE1 #FFFBDC

Square

Starting with #DCF2FF, each quarter turn (90°) takes you to the next hue: #FBDCFF, #FFE9DC, then #E0FFDC. Across the square, #DCF2FF pairs with #FFE9DC, and #FBDCFF with #E0FFDC.

#DCF2FF #FBDCFF #FFE9DC #E0FFDC

Tetradic

#DCF2FF and #FFE9DC are opposites, as are #E9DCFF and #F2FFDC. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #DCF2FF 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.

#ECF1FF

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.

#E7EDFF

Tritanopia

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

#D3F6F6

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.
