Ribbon colors for health care issues

I hope somebody can help me out. I know there are different ribbons representing the various health care issues---red for HIV, pink for breast CA, green for organ donation. I believe there are others out there but don't know all the colors what they represent. If anyone knows, or can direct me to a website that lists them all, I would appreciate it.
