I think the kryptonite has to be green in order to preserve the twist that it isn't normal kryptonite. And the supercomputer is too different to just call it Brainiac. It was designed and built on Earth rather than being extraterrestrial as it should be, and it was an actual computer as opposed to a green-skinned android. It's a little like saying the evil Superman is Bizarro just because he's an evil Superman. Where's the Bizarro logic? The white, craggy skin? He's simply Superman with a bad attitude, there's nothing particularly bizarre about him, which is the whole point.
