You're welcome, and yes, at most it lightens the color very slightly. I only did a single coat of RC though. I didn't want to use it up on multiple coats on a plastic wheel right now. I think my favorites are having it over the two Chanel Blues and Illamasqua Blow. For some reason, over Blow, it reminds me of the top of a cupcake. I get really hungry looking at it.
