Colors
Naturally colored cotton comes from pigments found in cotton pigments and produce shades ranging from tan to green and brown. Naturally pigmented green cotton derives its color from caffeic acid, a derivative of innamic acid, found in the suberin (wax) layer which is deposited in alternating layers with cellulose around the outside of the cotton fiber. While green colored cotton comes from wax layers, brown and tan cottons derive their color from tannin vacuoles in the lumen of the fiber cells.

Famous quotes containing the word colors:
“In Haydn’s oratorios, the notes present to the imagination not only motions, as, of the snake, the stag, and the elephant, but colors also; as the green grass.”
—Ralph Waldo Emerson (1803–1882)
“The butterfly’s attractiveness derives not only from colors and symmetry: deeper motives contribute to it. We would not think them so beautiful if they did not fly, or if they flew straight and briskly like bees, or if they stung, or above all if they did not enact the perturbing mystery of metamorphosis: the latter assumes in our eyes the value of a badly decoded message, a symbol, a sign.”
—Primo Levi (1919–1987)
“Few colors last; with their eternal thirst, time and light suck on them, and they bleach the black doctor’s hat until it’s grey like a dunce’s cap.”
—Franz Grillparzer (1791–1872)
