Aveda Phomollient & Hair color

Hi, Everyone,First of all, I would like to say that Phomollient is one of the best styling products I have ever used. It does not weigh down my fine hair at all, which is great. Its very light. I also like the fact that it does not contain those yucky chemicals mentioned in some of the other mousses out there. Speaking of chemicals, has anyone ever had their hair colored or highlighted using the Aveda hair colors, and if so, how was the result? I am sure that there really cannot be a "natural" hair color product, but I was wondering if they make their hair color with the same philosophy as their other products (ie., mostly plant products, organic when possible, etc.)? Karen, could you tell me more about the Matrix color that you use?Thanks, Clare
