To paint or not to paint.... that is the question

This house I just bought has 4 bedrooms all painted different colors.  I usually paint the entire interior on a rehab, but only because it always needs it.   The rest of the house looks really good, accent walls painted on the transition from the living room to dining room and kitchen.  In other words, it appears the previous owners had someone who was very skilled paint the house.  Everything is cut in perfect.  Its just different colors throughout. It does look pretty darn good.  Would you keep this on a  rehab?  The only thing it could use is some new paint on the interior trim.
