The right use of beige
I know varying shades of beige are very much the "in" thing right now in terms of wall color, but today I saw one of the best uses of beige in a property that I was showing.  It was in a very well-lit room with large windows, one that could tend to be a bit too bright if left white.  In this room, the use of a medium beige shade softened the light while still continuing to bounce it around the room, allowing the room to stay bright but not harshly so.

Another advantage, and probably part of why it's so popular right now is that neutrals are what you want to go with when you're trying to sell your house, so beige creates a way of having "color" in your home while still keeping it neutral enough for potential buyers to see it working with their stuff.

My advice is, if you're looking to have a beige room, stick with a very well-lit room which can benefit from the softening effect without getting too dark.
