#791109
sRGB · 121 / 17 / 9
#791109 belongs to the red family. Its hex code tells a screen to mix 121 red, 17 green and 9 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 4.3° lands in the red region. Its 86.2% saturation makes it strong in color at this lightness. HSL lightness is 25.5% on a scale from black (0%) to white (100%). Of black and white lettering, white has the clearer light-to-dark separation on this background (11.07:1), which helps the shapes of letters stand out.

Text contrast
Contrast tells you how clearly lettering separates from #791109 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.
Normal text: AAA
Large text: AAA
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. WCAG text contrast guidance
Palettes & scales
Harmonies rotate the hue. Scales mix the starting color with white, black or middle gray in 20% steps in encoded sRGB.
Complementary
#097179 sits half a turn (180°) from #791109 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.
Analogous
#790939 and #794909 sit 30° to either side of #791109. 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.
Triadic
#791109, #097911 and #110979 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 #791109 and look across the wheel. #097949 and #093979 sit 30° to either side of its exact opposite, giving you two different accent choices.
Square
Starting with #791109, each quarter turn (90°) takes you to the next hue: #397909, #097179, then #490979. Across the square, #791109 pairs with #097179, and #397909 with #490979.
Tetradic
#791109 and #097179 are opposites, as are #717909 and #110979. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.
Tints
Mixing #791109 with white in 20% steps produces this scale. The first mixture, #94413A, keeps 80% of the original. By #E4CFCE, the mixture is 80% white.
Shades
Mixing #791109 with black in 20% steps produces this scale. The first mixture, #610E07, keeps 80% of the original. By #180302, the mixture is 80% black.

Color vision previews
Compare how #791109 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.
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.
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.
Tritanomaly (50%)
An altered short-wavelength cone response can make blue harder to distinguish from green. This swatch shows the model’s halfway setting.
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.
