Choosing the right colour for your loafers depends largely on your personal style. The two most classic colours are brown and black. The original loafers were brown, but if you wear more black, that might be the right colour loafer for you.  Other neutrals such as navy, tan, or burgundy are great places to start as well. If you want to branch out and create an edgier look, you can try a loafer in a bright colour.
