Ok, did you wonder how it really looks like cut? I did plan for the cake to turn brown to contrast with the white and peach icing.
I should have been more patient. I used orange pop mica because I wanted soft orange icing. But when I pipped it it totally looked neon to me and I though it would mellow down. It didn't until 48 hours later (usually 24 hours later I would be able to tell the true color)! Anyway, this is what I had in mind so it is consider a success, phew!
