A gray bar does not necessarily mean that the site has been banned, in this case it most likely means that he has not yet been indexed, considering that the site is only a couple of days old.
A gray bar means either that it is not in the database because it hasn't been found yet, or it isn't in the database because it was banned.
A white bar means that it is in the database, but either has a PR0 or just hasn't been given a PR yet.
If you haven't done anything to have it banned, then there is always the possibility that the domain was used by a previous owner who had it banned. But considering the age of the .eu ccTLD, I'd say that this isn't the case.
