I bought these in the yellow and it's a good, deep yellow color - more mustard than peep/Easter yellow. I usually wear an 8 or 8 1/2. I got these in an 8 because I normally go down in open toed shoes - I have a narrow foot. These shoes are tight around the toes on me, so on the average foot or a wide foot, they'd be really tight. I'd suggest going up a 1/2 size.
