They're all very lovely
I especially love the coffee bean one. I'm a coffee holic.
As for the "natural" colorants. Have you checked the ingredients on your food coloring? Mine all contain some ingredients that are very far from "natural".
Being "natural" doesn't always mean being safe. There are a lot of "natural" ingredients I see people putting in there products that could be harmful or at least very irritating to the skin. Sometime's it is safer to go with lab created products, because they are manufactured in a clean and controlled environment.
When buying herbs and stuff for colorants just make sure you're buying from a reputable supplier. That's the easiest way to make sure you're getting a safe product. Actually, when buying any of your supplies, buying from a reputable seller is the best idea LOL
As for there being trace amounts of arsenic in some colorants. I have no idea. I've heard that almost everything we come in contact with on a daily basis (apple juice, water, rice, etc) have very small amounts of different things that could be harmful. But usually that's if you are in contact with large amounts daily, without washing it off. Since you'll most likely be using a very small amount of colorant and it'll be in a wash off product, the danger is very teeny tiny.
