I won't screw up on a Sato...

[A.S.]

I can tell you light green is "teh ZOMG pwn0rz", dark green not as much. Sea green is good too, I say in my opinion (PSO and "opinions" never go well together) Light green>Sea green>Dark Green. And yes you can get pitch black Satos (they are under dark blue, but don't let it fool you, it comes out pitch black) and I guarantee without a doubt, it's fugly. Ask Shiek how you thinks about his, I know he likes his.. for some reason :p

Black Sato below, thanks Shiek
