Yellow and Grey Guest Bedroom

Since I showed y'all the first finished guest bedroom, I figured I could show y'all the second (and final) finished guest bedroom.  I've seen so many ideas of combining yellow and grey, it inspired me to use these colors in this room.  Everything in this room is not new, but new to us.  I love to go estate sale shopping on the weekends; I always find awesome deals on the most random things.  One weekend, I purchased the entire bedroom set used in this room for only $40.  When I bought it, the whole set was this horrible, dull yellow.  I purchased some spray paint and went to town.  They turned out great!  The bed frame and the dresser are painted flat black, while the nightstand is painted yellow.  Just the perfect pop of color that this room needed.

The only thing that I am not happy with in this room is the wood trim.  It clashes with the colors of this room a lot, more so than in the orange and brown room.  I want to paint it white in the entire house, but I'm on the fence about it.  In one hand, it would definitely modernize the entire house.  On the other hand, it is real wood and I would be taking away from the integrity of the house.  What do you think? Paint it or leave it?
