A B/W randomart image which uses alphanumeric and special characters, like the one used in ssh-keygen itself when generating keys, would be enough. With current tech, Adding colors is just a recipe for disaster in environments which need maximum reliability. Personally, I think QR codes are just fine for manufacturing but as for encodings meant for end-users, I think we should be focusing on making them more human-readable or at least visually comparable, without sacrificing bit-depth. Still, this tech was really neat to play around with and I hope something good comes out of all the work put into it.
