It's hard to say for sure, look on the back and list which dyes are used and I can see if I have any notes on them.
I am not a huge fan of FD&C dyes. The few times I used them they stained the lather, the soap dish and the cools bleed into eachother. But that is a personal prefference of mine. I'm sure there are people who love to soap with them too.
