I don't have a lot of Amplifieds, but as far as I can recall, it's creamier and glossier than the ones I can think of - almost like a sheen supreme but with double the pigment.
I definitely have some yellow undertones to my skin in there, because certain colors make me look very sallow. I couldn't resist RS, even though I'd brought my tube of Jazzed in to the store to compare it and it was exactly the same color, just a different finish. Even Jazzed I can only really pull off well at the height of the summer when I'm at maximum sunburn face and the light quality in L.A. is very bright and penetrating. Come to think of it, I honestly would only wear Jazzed in the daytime too, on top of it.
Good thing I'm sometimes in the mood for a very in-your-face, wacky lipstick. I admit I get a little inner thrill when I catch someone looking all perplexed and shocked at my lipstick
