#DCF1FA

sRGB: 220 / 241 / 250

Thunderous oceans pierce eternal darkness
Unbridled forces disappear beneath stillness
Celestial symphonies illuminate hidden worlds

#DCF1FA belongs to the azure family. Its hex code tells a screen to mix 220 red, 241 green and 250 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 198.0° lands in the azure region. Its 75.0% saturation makes it strong in color at this lightness. HSL lightness is 92.2% 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 (18.01:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #DCF1FA 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: 18.01:1

Normal text: AAA
Large text: AAA

White text: 1.17:1

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

#FAE5DC sits half a turn (180°) from #DCF1FA 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.

#DCF1FA #FAE5DC

Analogous

#DCFAF4 and #DCE2FA sit 30° to either side of #DCF1FA. 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.

#DCFAF4 #DCF1FA #DCE2FA

Triadic

#DCF1FA, #FADCF1 and #F1FADC are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#DCF1FA #FADCF1 #F1FADC

Split complementary

Start at #DCF1FA and look across the wheel. #FADCE2 and #FAF4DC sit 30° to either side of its exact opposite, giving you two different accent choices.

#DCF1FA #FADCE2 #FAF4DC

Square

Starting with #DCF1FA, each quarter turn (90°) takes you to the next hue: #F4DCFA, #FAE5DC, then #E2FADC. Across the square, #DCF1FA pairs with #FAE5DC, and #F4DCFA with #E2FADC.

#DCF1FA #F4DCFA #FAE5DC #E2FADC

Tetradic

#DCF1FA and #FAE5DC are opposites, as are #E5DCFA and #F1FADC. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #DCF1FA 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.

#ECF0FB

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.

#E7ECFA

Tritanopia

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

#D4F4F4

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.

#E6F0FA

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.

#E4EEFA

Tritanomaly (50%)

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

#DBF2F8

Grayscale (luminance)

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

#EDEDED
