Open Question: Trying to sell a....?

Trying to sell my home. My house is small and pretty boring without the color. The living areas and hall are chocolate brown, I am painting all bedrooms beige or tan, the kitchen is a warm red and I am repainting the outside gray but it turned to the blueish side once I started painting. So.... Should I keep the red? Should I keep the brown? Should I worry about the exterior paint looking too blueish? Would any of that hurt my resale value if you were considering buying my house?
