Got a bit of a problem...

ok so i am thinking about getting both the wi and the ps3 but the thing is my tv wont show color when i want to play games!!! it is in black and white, and i don't know what to do. i don't wanna switch it because i have a dvr and lots of wires that go far beyond my room that are hooked up to my tv!!but i really want the color! do u know what i should do?
