There are tons of options. Are you wanting a particular brand? A light tan will be the obvious option, but there are a bunch of those. Best thing to do is go to the store and pick up swatches.
Pics in my blog of our nursery so far. We painted the walls a tan/taupe/beige color w/ white trim and we're doing espresso furniture with cream/white/brown bedding and light blue and orange accents.
