#BF330C

sRGB: 191 / 51 / 12

Ancient mountains reshape eternity
Solitary lanterns flicker through endless evenings
Lost whispers awaken sleeping galaxies

#BF330C belongs to the red family. Its hex code tells a screen to mix 191 red, 51 green and 12 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 13.1° lands in the red region. Its 88.2% saturation makes it strong in color at this lightness. HSL lightness is 39.8% 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 (5.68:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #BF330C 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: 3.69:1

Normal text: Fail
Large text: AA

White text: 5.68:1

Normal text: AA
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.

Complementary

#0C98BF sits half a turn (180°) from #BF330C 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.

#BF330C #0C98BF

Analogous

#BF0C3E and #BF8D0C sit 30° to either side of #BF330C. 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.

#BF0C3E #BF330C #BF8D0C

Triadic

#BF330C, #0CBF33 and #330CBF are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.
