Nope, the August fish were pretty white on the bottom. And, FWIW, they were from a West side river and a few days to a week (I suspect) from the salt water. Certainly not as colorful as the fellow above, but my point was color isn't particularly diagnostic of anything in steelhead (in my completely untrained opinion). I'm not sure about Temperature effect on color, since I would swear that unless fishing really close to end of the lifecycle (late March and on), the fish I catch generally look the same from about October onward. This true on the GR and on rivers well downstream (Umatilla, Touchet, Tucannon, Walla Walla, etc.) I could make stuff up, but honestly I have no idea why.
