Go to home depot and ask for a sample can of paint they can make any color for u and it cost 3 dollars. Its latex paint so it will peel right off if you want to change it. Each sample can will have more than enough to paint a 60 gal
+1 Just plasti-dipped my 55 gallon and it looks great. I needed 1 & 1/2 cans for the job. It's really easy to peel off too if you decide you don't like it.
