A false color picture aquafishy. There are no angels exactly like that.
The closest to that particular color pattern is either a silver, who would have a silver body and black stripes, or a gold, which would have an all gold body. My guess is that was a picture of a mature silver, which would likely have a gold crown (mature angels will have a "crown", which is a darker area from the nose to the dorsal fin. Its usually gold/bronze/yellow), who's dark bars had faded under stress (the silvers will do that). The more I look at it, the more sure I am its just a poor picture of a silver; you can see the black bar thru the eye, which doesn't fade on silvers, is not seen on golds, and is a defining factor for the silver.
