It is a henna based color. I wouldn't touch it. And I am always leery when a manufacturer can't spell the ingredients correctly. "Indigofera Tinctoria, Lawsonia Inermis, Emblica Officinails Gartn [sic]" (Emblica Officinalis Gaertn)

This is Indigo dye, red henna and a dye fixative respectively. In my opinion I don't see how they are getting all those other colors out of just Indigo and red....makes one wonder if this is indeed a "Compound Henna" which does come in many color but contains metallic salts, even though this one says it doesn't. But just based on the fact it is a Henna I would not use it.
