Hi there-
I LOVE LOVE LOVE the Nobara creme. this and the makeup forever f&b are really the only two I use nowadays. I have 5 colors...let me look in my kit.....
ok, i'm back, here's what I have...564, 983, 314, 545, 754. These range from super pale beige to darkest (red undertone). They mix really well together. As far as the rcma thinner goes, I can't tell ya since I don't use it. I will tell you though that I mix them with regular moisturizer (usually Kiehl's) and never have a problem.

hope that helped you..
