A fresh clean look in pale wood feels modern while referencing the 50's. The pared down look is inviting but not boring with the addition of the bright spot of orange in the lamp sitting on the built-in dresser.
If you dislike the color of your carpet and cannot change it, embrace it. Do not work against it. Choose a paint color that complements the existing floor covering. This bedroom's blue-gray carpet may have looked odd if the decorator had decided to ignore it instead of working with it.
