How can I dye almost black hair naturally or temporarily?

I have almost black hair. Meaning it's very very dark brown. I need a way to either temporarily dye it a different color or naturally dye it a different color.How can I dye almost black hair naturally or temporarily?
You will probably have to dye it a much lighter color like blonde and then the color you want. But a salon is the best to go to for that so you don't end up with really funky hair.How can I dye almost black hair naturally or temporarily?
You can just go to a salon and they'll do it for you. But why would you want to dye your hair? Mine is naturally black and I like it.
