So, we decided not to find out the sex of our first child. I really have the urge to paint the bedroom gray, not dark gray, but a light gray. I thought this would be a great neutral color because it would be easy to accent it with greens and yellows. I'm having several people telling me that gray is such a cold color and you don't want that for your baby's room. I'm torn but I would like some opinions! 
Thanks!
