Is sepia a color? It has been explained to me in a variety of ways. Kinda brownish, tan, cinnamon, nutmeg, rust, reddish brown, brunette, khaki, mahogany or it just makes photos look old. In grade school, was there a sepia color in my crayon box? Very confusing for someone like me who struggles with colors. Regardless.....this sepia sunset provides an interesting look to this photo, no matter what color you may call it.
