Much like DeviantART isn't Google or Photobucket, DeviantART isn't a colouring book. If you see someone's shiny lineart either newly uploaded or in their gallery, don't think "hey, that looks nice, I'll colour it!"
It's not your artwork to take and colour.
By all means, if it's in a club that specialises in lineart that is available for others to colour then, with any appropriate credit required by the artist and / or club, colour it. But if it's someone's own, personal gallery, the only thing you will do is annoy them.
If you really, really want to colour some of their work, drop them a note and ask. The worst they could do is say "sorry, I don't let people colour my artwork". But they might say "yes", or "we could collaborate instead".
But simply taking it, colouring it and uploading it again, whether you credit or not? That's theft.
same with comic/manga books. like the actual book you buy from the store. and then people go coloring in them like it's a coloring book. gah. it's just ruining it.
I have never ever come across someone who has said "no" to me colouring their lineart. It's more of flattery than theft. What are you appropriating? You haven't "taken" anything, but that's only under the considerations that you give an original link back to the lineart itself. There have been a few occasions where I've coloured someone's lineart as a "surprise" for them, and they had no problem with it afterwards. This assumes to much that applying colour to some lineart breaks the rules of copyright, when it doesn't.
