I haven't had ample time to try these out yet, but I have done some swatches for you.  

Hayden is a very neon orange, I never thought I would say that. It is very bright but creamy in tone. It does not go on easily, it takes a lot of work to get it smooth. Leah on the other hand went on really nicely but then peeled off within the day. I am not sure if these were just mu first time uses of the colours but that is about all I know about how they go on at this point.
