How can I dye my faux fur Pink and Purple?

For Halloween this year, I am going to be the cheshire cat. Unfortunatly, I do not know a scooby about dying fur or.. well.. anything! I am 14, but the good thing is that I can sow. I also do not have dye of anykind, but I can get my hands on paint. I have 3 sheets of white faux fur so I basicly have only 1 chance.
