I'm not sure how I would implements changing default colors so that it make sense in the UI tho. Also remember that colors are different per indicator type so you would need to do six indicator types which can be pretty annoying. I think the "Imports colors from another indicator" thing I have planned will be enough for now. Once you have a new indicator created or are editing one, you will just be a few clicks away from having the same colors as any other indicators you already have on your dashboard. I think it will be good enough for now and I will be able to move on to other stuff... at least for now :P
