My father has passed away of renal (kidney) cancer and I would like to get a tattoo of the awareness ribbon and his dates. I've looked on multiple sites and some say green is kidney cancer while others are saying orange is the correct kidney cancer ribbon. Does anyone know which one is accurate and let me know how they know its accurate? Im hearing that it used to be green but has changed to orange but I'm not sure how true this is. Answers are greatly appreciated! Thanks!
