#B1C19D

sRGB: 177 / 193 / 157

Ancient mountains dissolve into silence
Majestic waterfalls disappear beneath stillness
Rising tides shatter the chains of fate

#B1C19D belongs to the yellow-green family. Its hex code tells a screen to mix 177 red, 193 green and 157 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 86.7° lands in the yellow-green region. Its 22.5% saturation makes it close to gray at this lightness. HSL lightness is 68.6% 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 (10.98:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #B1C19D 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: 10.98:1

Normal text: AAA
Large text: AAA

White text: 1.91:1

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.

Harmonies rotate the hue. Scales mix the starting color with white, black or middle gray in 20% steps in encoded sRGB.

Complementary

#AD9DC1 sits half a turn (180°) from #B1C19D 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.

#B1C19D #AD9DC1

Analogous

#C1BF9D and #9FC19D sit 30° to either side of #B1C19D. 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.

#C1BF9D #B1C19D #9FC19D

Triadic

#B1C19D, #9DB1C1 and #C19DB1 are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

Color vision previews

Compare how #B1C19D 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.

#C5BC9B

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.

#C3BB9F

Tritanopia

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

#B3BDB7

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.
