Open it in Photoshop or GIMP, make it white by desaturating and save it again as PNG. Once in Unity you can choose whatever color you want.

Hi, sorry if this is a silly question (i'm new to this), I can see the sprites used in this are purple, but I'd like to change them to a blue colour; is there an easy way for me to export the sprite so I can change its colour?
