I would go to a place that sells paint and look at the sample swatches. Pick several you like, then go home and try to imagine the room in thatcolor, but with your stuff in it. I did an entire house that way and it turned out great! Got some unexpected colors, but looks nice. No one can really choose but you. My daughters chose and old rose color for their room, REALLY pretty.

Light blue or something ligjt will be nice ^^ makes your room sounds cheerful and peace.. hahaha! For me la~

Go with light colors but stay away from Yellows and Reds .. Baby blue and Baby pink is cute and you can decorate it with sun and clouds ^^

If you likes to look girly, combination of white color with baby pink color. Baby blue is awesome too.

Light blue or mint blue. I'd paint it that way
