What should I do to my home? PLEASE HELP!!!!?

I have 3 rooms that run right behind one another. When you walk into my house you walk directly into the living room, next is the dining room and then the sun room or family room, in my mind the tv room. The living room walls are feverish pink with white wainscoting, chocolate brown couch and cream colored chairs, rug is also a cream color and the book case and sofa table is a dark wood as is the legs on all the furniture. What color should I put into the dining room and tv room without being to matchy matchy? I want everything to be cohesive, without having all the same colors in each room. My kitchen sits off by itself but it has white cabinetry, with a soft pastille yellow paint. The countertops are stone tile, grayish color which matches the floors. Does this go with the rest of the house or should I change the kitchen to a warmer color including the cabinetry?
