I bought them especially for dark colored clothes that permanent marker won't work on.

I wish there were some that were bright colors, but white works for most.

Most of my son's jackets and hoodies are darker colors, and black permanent marker doesn't show up on them very well

One of the labels was applied to a white part of overall dark colored shirt, and after I washed the shirt with other dark clothes, I could see some darker colored fuzz stuck to the edge of the label
