You mentioned the color of the brown trout originally shown. This trout was right out of the hatchery truck, since I caught it in a delayed harvest stream. However, the varied colors of brown trout amaze me and is one of the great pleasures of catching them. The differences in color may lie in whether the trout came from the german strain or scottish strains that were originally brought to this country. Or it may have something to do with habitat and diet. I caught a brown on the NC side of the park two weeks ago that was almost pure silver, with a few vey faint spots. I did a double take on this fish because I first thought it was a rainbow.
Contrast that with the brown I was lucky enough to catch this weekend on the Nantahala.
Treasure every brown, because every one is unique.
