I catch a fair number of wild browns this time of year with that silvery salmon look about them, mostly in tributaries to the three big reservoirs that serve the Baltimore region, but also in streams with sandy bottoms.
This one's got a little more color than the brown that sparked this thread, but compared to other wild browns in the Balto area, it is very pale:

It came out of maybe the second or third to last hole with flowing water going into the reservoir and the creek has a very light, sandy bottom at that location:

Got a wild brown in one of the branches of Codorus that runs into Lake Redman a few years back on a day when there was snow on the ground. It was very silvery.
And occasionally I pull a silver wild brown out of a sandy hole in non-reservoir stream, typically in wintertime.
Meanwhile, a more typical Maryland wild brown in wintertime looks like this one from Antietam Creek:

I have two theories, based on absolutely no scientific research:
- Though they can't change colors like a chameleon or squid, I believe when a trout takes up residence in a spot, its colors get darker or lighter depending on the particulars of the spot. I also believe there's a seasonal component because there's no leaves to shade the streams in wintertime, by late winter, the fish turn more pale to match the more brightly lighted stream bottom. My musings are based on noticing that stocked brown trout in particular start out with that hatchery coloration but by late autumn have picked up a more natural look (though this could be a purely spawning season related).
- Also, I believe that the wild browns with dark colors that head for the open water of Liberty Reservoir (or one of the other big lakes) turn silvery, and revert to darker shades when they return to the creek, like sea trout and salmon.
Possibly Mike will weigh in on the validity of my cabin fever musings.
Also, a word on the sampling technique: I fish with Panther Martin spinners in wintertime because daylight is limited, the trout are few and far between in the streams I hit, and I need to cover a lot of water fairly quickly.
I don't apologize. That's my life.
