[Fluken-Around]

I worked for a private trout hatchery in Pa for many years. In late January we would change there feed so in April when you catch them there flesh has that pink or orange tint that everyone relates to a native trout. If my memory serves me right it was a shrimp base feed that turned them that color not a dye. That feed was more expensive so we only fed them that feed a few months proir to when the majority of fish are stocked then would switch back to normal feed.
