HELP changing interior immediately

I have a navy blue 89 Buick Century and the interior of my car is navy blue but to me the inside is really plain. I want to change the color and make it different because I like different things but I also want it to look good and match. I would like anyones opinion on this one, I need advice on color and materials and I actually need to know how to go about doing it myself because I don't have the money to go get it done. The only reason its so hard for me to think of an idea is because my seats aren't leather or anything so what do I do please if ANYONE have any advice for me please I would love to have any advice and help from everone asap
