What does the throat cancer ribbon and the melanoma ribbon look like?
According to the “for the cure” site melanoma is a black ribbon. It doesn’t list throat cancer. But it also doesn’t list lung cancer, so it doesn’t appear complete. The Trinity London site and the Pin People site also have black for melanoma, and “pearl” (opalescent?) for lung cancer. Purple is the color for cancer survivors, but would be more appropriate for your parents than for you. That tattoo is really a lovely idea… I’m sure you’ll come up with whatever is just right for you, and no matter what it is, your parents should feel honored by the fact that you did it.
