Here's an easier way to recolour: using the colour picker thing, choose the color you want to change. Then, still with the colour picker, right click the color you want to change it to. Next you just choose the eraser, and hold down right-click while moving the eraser over the old colour. It will only replace the old colour with your new one so you don't have to worry about making it just a big spot of colour instead of a sprite.

I feel that this way is MUCH more efficient and MUCH easier to do, but do whatever you think is best!
