Yes for the most part they are a "mustard yellow". However there can still be nicer ones. Think about some Grey Poupon dijon mustard, kinda plain brownish yellow. Then think of Heinz brand, a sharper mustard yellow. Just keep it in a clean, natural state and it will eventually show it's true colors whether they are nice or not.
The only way to save a browned out coral is if it's currently in a system with too high of nutrients and you then correct that problem, it can "brighten" up a bit. Chronic low nutrients may lighten it as well but that is going to set up other hurdles for you to jump. However if the system it's in has optimal parameters then that's just the color it is, sometimes you have to get lucky.
