#0DEDBB

sRGB: 13 / 237 / 187

Hollow echoes command forgotten kingdoms
Immortal legends illuminate forgotten empires
Eternal flames defy the passing ages

#0DEDBB belongs to the cyan family. Its hex code tells a screen to mix 13 red, 237 green and 187 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 166.6° lands in the cyan region. Its 89.6% saturation makes it strong in color at this lightness. HSL lightness is 49.0% 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 (13.85:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #0DEDBB 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: 13.85:1

Normal text: AAA
Large text: AAA

White text: 1.52:1

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

#ED0D3F sits half a turn (180°) from #0DEDBB 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.

#0DEDBB #ED0D3F

Analogous

#0DED4B and #0DAFED sit 30° to either side of #0DEDBB. 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.

#0DED4B #0DEDBB #0DAFED

Triadic

#0DEDBB, #BB0DED and #EDBB0D are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

Split complementary

Start at #0DEDBB and look across the wheel. #ED0DAF and #ED4B0D sit 30° to either side of its exact opposite, giving you two different accent choices.

#0DEDBB #ED0DAF #ED4B0D

Square

Starting with #0DEDBB, each quarter turn (90°) takes you to the next hue: #4B0DED, #ED0D3F, then #AFED0D. Across the square, #0DEDBB pairs with #ED0D3F, and #4B0DED with #AFED0D.

#0DEDBB #4B0DED #ED0D3F #AFED0D

Tetradic

#0DEDBB and #ED0D3F are opposites, as are #0D3FED and #EDBB0D. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #0DEDBB 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.

#E6DCB8

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.

#CECBBE

Tritanopia

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

#00EFDF

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.

#BDE0BB

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.

#B1D7BD

Tritanomaly (50%)

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

#0FECC8

Grayscale (luminance)

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

#D2D2D2

Partial grayscale (50% blend)
