Okay, so I figured I'd post back up the simple colored paint recipe earlier. About as straight forward as they come.
Step one: buy a can of white paint. I use ace oil based tint base, as it's made specifically to be tinted, but any white paint should work. Oil would would be preferable though...
Step two: buy a can or tube of paint tint. This can sometimes be kind of hard to get a hold of, without knowing someone at a hardware or paint store, but you can buy a kind called Sheffield Bronze Tints-all online quite easily.
Step three: crack open can of paint and pour into your container of choice.
Step four: add tint. Be careful, a little goes a long way, but if you over do it, then the tint, which is generally very thick, can clog the nib on whatever mop you're using as well as prevent the paint from drying.
Step five: add your choice of paint thinner, mix, and enjoy.
