#BDFFDF

sRGB: 189 / 255 / 223

Ancient mountains command forgotten kingdoms
Unbridled forces transform the fabric of existence
Fierce revelations echo beyond eternity

#BDFFDF belongs to the green-cyan family. Its hex code tells a screen to mix 189 red, 255 green and 223 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 150.9° lands in the green-cyan region. Its 100.0% saturation makes it strong in color at this lightness. HSL lightness is 87.1% 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 (18.53:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #BDFFDF 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: 18.53:1

Normal text: AAA
Large text: AAA

White text: 1.13:1

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

#FFBDDD sits half a turn (180°) from #BDFFDF 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.

#BDFFDF #FFBDDD

Analogous

#BDFFBE and #BDFEFF sit 30° to either side of #BDFFDF. 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.

#BDFFBE #BDFFDF #BDFEFF

Triadic

#BDFFDF, #DFBDFF and #FFDFBD are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

#BDFFDF #DFBDFF #FFDFBD

Split complementary

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

#BDFFDF #FFBDFE #FFBEBD

Square

Starting with #BDFFDF, each quarter turn (90°) takes you to the next hue: #BEBDFF, #FFBDDD, then #FEFFBD. Across the square, #BDFFDF pairs with #FFBDDD, and #BEBDFF with #FEFFBD.

#BDFFDF #BEBDFF #FFBDDD #FEFFBD

Tetradic

#BDFFDF and #FFBDDD are opposites, as are #BDDDFF and #FFDFBD. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.

Color vision previews

Compare how #BDFFDF 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.

#FDF6DD

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.

#F1EDE1

Tritanopia

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

#AFFFF6

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.

#E9F8DF

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.

#E3F4E0

Tritanomaly (50%)

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

#BEFEE7

Grayscale (luminance)

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

Partial grayscale (50% blend)

This design check mixes the original color halfway toward its grayscale equivalent in linear light. Use it to see how a design holds up as color fades.
