How do I dye Black and White Nike Elite Crew socks so they have a pink stripe instead of white?

I have authentic Black and white nike elite socks. I want to make them so the stripe running down the back of them is breast cancer pink. If possible please include links or sites where I could get the dye. Also please leave step by step instructions on how do dye them. Thanks in advance!|||You could try washing them with newly bought red clothing items ?
