On the other hand, white is timeless and you can bleach it. If you have natural light in the room, you may also want to think about which direction the light comes from. Go to a good paint store and pick their brains. Flip through some magazines and look at bathrooms that have cabinet work similar in colour to yours to get ideas. Whatever you do, take the time and put up with the nuisance of doing some test patches. It's always worth it. If you find something you love in a paint strip and you just can't stand to do the test patches, get a shade or two lighter than the colour you think you want. When it is on the walls it will 'read' as the colour you originally wanted. Light or dark, the effect will intensify in a small space. If you find a lovely light flattering shade, do the ceiling the same for a seamless look that will flatter you from every ange and expand the sense of volume in the space. You've done a wonderful job on this space. Look in your closet an think about the colours that look great on you. That's a great way to pick a colour scheme for your accessories. Another suggestion: all the major paint lines have very interactive web sites. You can load your own pictures into most of them, and then test their colours on your own walls. Some allow you to test with daylight or artificial light so you can find something that will look good in both.
Have fun. Sorry this is so long. This is so my kind of project!
