#1EBDFD

sRGB: 30 / 189 / 253

Fading shadows fracture ancient heavens
Restless constellations illuminate forgotten empires
Celestial symphonies shatter the chains of fate

#1EBDFD belongs to the azure family. Its hex code tells a screen to mix 30 red, 189 green and 253 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 197.2° lands in the azure region. Its 98.2% saturation makes it strong in color at this lightness. HSL lightness is 55.5% 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 (9.75:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #1EBDFD 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: 9.75:1

Normal text: AAA
Large text: AAA

White text: 2.15:1

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

#FD5E1E sits half a turn (180°) from #1EBDFD 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.

#1EBDFD #FD5E1E

Analogous

#1EFDCE and #1E4EFD sit 30° to either side of #1EBDFD. 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.

#1EFDCE #1EBDFD #1E4EFD

Triadic

#1EBDFD, #FD1EBD and #BDFD1E are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#1EBDFD #FD1EBD #BDFD1E

Split complementary

Start at #1EBDFD and look across the wheel. #FD1E4E and #FDCD1E sit 30° to either side of its exact opposite, giving you two different accent choices.

#1EBDFD #FD1E4E #FDCD1E

Square

Starting with #1EBDFD, each quarter turn (90°) takes you to the next hue: #CE1EFD, #FD5E1E, then #4EFD1E. Across the square, #1EBDFD pairs with #FD5E1E, and #CE1EFD with #4EFD1E.

#1EBDFD #CE1EFD #FD5E1E #4EFD1E

Tetradic

#1EBDFD and #FD5E1E are opposites, as are #5E1EFD and #BDFD1E. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #1EBDFD 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.

Tritanopia

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

#00CED3

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.
