I know this after a woman I know swears up and down her dog was specifically part chocolate lab, and science be damned, that was the only color she was mixed with.

Labs have two genes that control colors. one gene controls color the way a switch controls a light: turns it on or off. If that gene is recessive, you have a yellow lab. Otherwise, brown or black will dominate. So, a yellow lab may be either brown or black; just that the color is turned off.
Edited to correct my stupid spelling/typing!!
Just one of the 2 1/2 things I remember from a genetics class in grad school!
