About Auburn
Auburn (#6D351A) is a dark, moderately saturated shade of brown. Its hue angle is 20°, which places it between red at 0° and orange at 30°, nearer to 30°. In RGB it is mixed from red 109, green 53 and blue 26, that is 43%, 21% and 10% of each channel, so red leads the mix. In HSL terms that is 20° hue, 61% saturation and 26% lightness.
