thanks for replies all
Yann, now that I tried opening your cap I realised you used a plug in..
When you sent me this in chat I didn't know.. I was so confused as to how you did it.. cool though
also kbd.. I'm not sure I understand you? Are you talking about making sprites the right colours in photoshop beforehand? Because if so that's not what i'm after.. I'd like them.. uhh "dynamic" if you know what I mean :p
