I always feel like my gold toe black socks lose their color and become gray, which annoys me. I need to find something better... I had purchased some Donna Karan socks from a NM Last call, which kept their color but fell apart after about 6 months. Viccel's dark color socks are indanthren dyed which has the highest fastness. No matter how many times they washed they will keep their colors. Blacks will be black.
