Naturally colouring Synd shampoo bars

[Jillyb]

Ive heard oxides can smell bad pink clay can affect hair colour.. etc, etc..
Would love to know what you colour your shampo/conditioner bars with as a natural colour.
Edited title for clarification.

Do your research and see what commercial shampoo makers use to color their shampoos for hair. Remember some colors will enhance and some colors will badly stain gray hair. Blues and purples will whiten gray hair and help pull out the greenish cast from blond hair created from chlorine. Henna can help brighten reds and browns, walnut browns etc.

Thanks. My research is confusing/conflicting info etc. I find most commercial shampo bars dont clearly identify what dye/colourant is used . So hope some have personal experience thay can share. I use neem powder for my green which is great.. pink clay for my pink (less than 1%) but read today it can cause blonde hair to go off colour.
I use a multitude of different natural colours in my HP soap but saponifcaction changes how coloues work, last etc synd shampo seems to be a lil different.
