Unfortunately henna and herbal stuff is the only way to go with hair color for anything remotely natural. If you are bored one day, you can try hibiscus tea for red highlights, black tea or apple cider vinegar for brunette highlights (try sitting in the sun for that one), or lemon juice (also helps being in the sun) for blonde hair.
I saw some herbal dyes in the natural shops and Whole Foods. You can grab whatever colors you like and tell your haircare professional to do it for you. That way it'll be a treat for you and your hair.
