I use Color by RC, and I use CK under gel. I haven't really ever noticed any fading, I don't need to refresh my overall color very often. I do try to keep the CK off the roots after a fresh color JIK. It's worth a try, as it really defines the curl.

But then again, after seeing your pineapple thread pics, I don't think you need to make any changes -- perfect!
