Hello. Have you seen the 3pi robot? This is a fully assembled robot that you can program to do line following. We have example code for it that does line following.
If you just want to get a sensor and build the rest of the robot yourself, check out our QTR sensors which are listed on this page:
pololu.com/catalog/category/7
I don’t know if the 3pi or the QTR sensors would work with green/white and pink/white, but you could try it.
