Usually, a lighter colour light white is easiest to do. Throw gloss in the mix and it becomes trickier again. That said, satin black is a great finish. It's easier to keep clean than gloss black. Gloss black is a bitch to do and it gets fnger prints all over just by looking at it. On the flip side, if you get some small scratches, you can polish them out as it is only the gloss which is scratched. With Satin, once its scratched, it's scratched.
Anyway, I'm just rambling. I'm not trying to change your mind, Devo, as I love the satin black finish and I'm sure it'll look great.
