Karen, what color shampoo do you use?

Hi Karen,I was reading the reply several posts down you had to Kara, about highlighting your hair and using color shampoo between highlights. Your hair is very similar in color to mine, and I have highlights put in every 6 months or so (they use foil though) and I was wondering what kind of color shampoo you use to help brighten up the last few weeks between highlighting. I have always been afraid to use these, for fear my hair would turn orange or something! Thanks Karen, I love your site. Ellen
