Hi Jonas,
In the next phase you pick five designers, based on their work, you want to work with. You ask for modifications, revisions etc if you have any. You can always change that five designers you want to work with.
In the Judging phase though you only continue with that five or any five you like on their provided concepts only meaning no new concepts -supposedly :) by putting one of the on the 1st rank. In this Judging phase only nr1 ranked designer can submit entries so you bring any designer to this position you want to receive an entry from.
Once you settle then you declare the winner. Get your files -some even send extra files of all kinds. And approve so that the winner can receive the prize amount.
Recoloring, or doing minor changes should not be an issue with any designer here even after the contest in case you change your mind.
That's all basically. In case you need more info on this you can check here:
