Looks pastel to me but whether or not it's significantly browned out is hard to say from that picture. It could be dusty from the bedding or nearing a shed cycle. I can't really tell without a good view of the animal's sides. Even browned out pastels usually have a lighter yellow near the base where their sides meet the belly. Since that picture doesn't show this view it's hard to say exactly how browned out the snake in question is.
