The browns in leaves after all colors have disappeared is caused by the pigment tannin. Tannin is present throughout the growing season but masked by the chlorophylls (greens), xanthophylls and carotenes (yellows and oranges), and anthocyanin (reds and purples).
Tannins are used in leather refining processes.

Tannin
Tannins are astringent, bitter-tasting plant polyphenols that bind and precipitate proteins. The term tannin refers to the use of tannins in tanning animal hides into leather; however, the term is widely applied to any large polyphenolic compound containing sufficient hydroxyls and other suitable groups (such as carboxyls) to form strong complexes with proteins and other macromolecules. Tannins have molecular weights ranging from 500 to over 3,000.
