The blessing of white is that it goes with anything. I would think the furniture would be more of a consideration in color choices.
Go with colors that make you smile when you look at them!
I have the bedroom in our DP painted now and went with a southwestern theme. I actually totally gutted it with the exception of the cabinets. Really cozy in there. I smile and think how much I love it in there each time I am in the MH.
One mod leads to another so:
The bathroom I painted also and put mosaic ties on the wall around the sink above the "splashguard" I also found some tiles "6x6" that i used for art on the walls. Painting really was easy. I did use the paint with primer included. Also washed down the walls prior to painting. Also put cork tiles down on the floor after pulling up the off white carpet. (Quite a learning curve there!) Who'da thunk they would put carpet down THEN put the walls on top of it!
Still have the front to do this spring! Different ideas still floating around the back of my mind, waiting for one to come forward as the plan.
So back to the original question, painting is easy, pick colors you love that work with what you are not changing and start painting!
