Still waiting to find out the gender but we actually picked a neutral color for the nursery. Since brown is a base for both trends in color (pink and brown for girls and blue and brown for boys) we went with a color called 'warm caramel' it's the last one on the chart below.
It's actually a very pretty color on the walls and looks great with the new carpet and baby furniture. Russ has it about halfway painted so I'll post pics when it's finished and the carpet is in etc.
