You can get the filters at freestyle. To judge the color balance you need some viewing filters (also freestyle) or a keen eye that will tell you how much you need to change your filter pack. It's pretty simple to use the filters but it will take you a few test prints to get the correct filter pack but once you have it it should be the same for your whole pack of paper. When you change paper batches you will need to re test.
Give it a shot, it's easier than b/w printing imo.
