Hello! I was wondering how you do that multi coloured line art with the sort of gradient? I see a lot of artists using it on tumblr, is it a case of just separating your line art?

cottonbun:

The easiest way is to lock the lineart layer (so, yes, that means that it should be separate) and use a soft brush (any kind will do) to colour delicately over the lines. 

I hope that answers your question, Nonie?
