Winter steelhead can show a preference for colors in fly patterns. I have personally caught winter steelhead on flies that are predominantly black, brown, red, orange, green, chartreuse, tan, straw, purple, and colors I have forgotten. In my experience there are two very significant characteristics of a fly that can prompt a reluctant steelhead to bite. This is one of the reasons I suspect egg patterns are so effective. Not because they imitate an edible fish egg, but because they are small.
Size can have overriding appeal.
