Hunters have many options open to them. We are still on point about color and not what the garment is made of.
I know from observation at the many Dirttime events we see all kinds of choices being made. From hi-tech camo to desert tans, white, red, and black to coyote brown. We all have our colors we seem to be drawn by. I feel what we have to keep in mind is the function or end use of the color and how that will benefit us. Do you want to enhance or blend into the background.
Blue jeans and a white T-shirt will work some of the time. I favor plaid shirts in all colors except yellows. The right blend of colors in a plaid shirt are very much like camo under the right conditions. Pants I favor range from black to gray to tans and browns. But that's me as I tend to like the “traditional” .
Oh yes the “High” end user clothes were always there, and the colors were sometimes a subtle difference from the run of the mill. Today many high end clothes have their label plastered all over the clothes.
