Modest little request about staff

[James tthe lighthearted]

Well, I'm refering to how once you get a staff, you are stuck with the color of spells the staff produces (like warped staff makes your spells have a greenish tint). When you get the harrows staff at level 15, everything looks grey or white (not including the flames skull, it looks the same on everyone of the staffs). I think it would be a cool feature to choose the colors of the spells your staff produces, kind of adds a little flavor into the staff.
