I saw this on twitter, it is a product called color bug, and gives you the fabulous dip dye tips in fun color such as pink, purple, and peach. I sent an email to Kelly who sells it in her salon, and the pink arrived and I am excited to try it out! If you want it I really recommend going through her, because it is super difficult to find online.
I think it will be fun for a casual night out but add some glam. I really wanted peach a la Lauren Conrad, but don't think it will show on brown hair
