Cryptomeria often develop bronzing or russeting in winter. It is a condition known as photoinhibition, the result of high light levels combined with low temperatures, and temporarily affects the pigmentation. It is very common with many cultivars of C. japonica.

Provided those bronzed needles are still very soft and flexible, I doubt there is much to worry about. They should green up properly as temperatures warm.

@gardengal48 (PNW Z8/9) Any problem leaving these outdoors when we are having a heavy rain season here? I assume the bronze coloring signals they were someplace cold, and they are probably going into a much warmer environment here where the nighttime temperatures are rapidly moving towards 50F. I imagine these are well equipped to handle winter conditions, but likely they were in a nursery-controlled environment and now are moving into a warmer place where they will be constantly watered.
