This is why I gave mention of the other foundation. I'm genuinely too pale for anything from Tom Ford and I'm not mixing it with it with white so when I saw Cream again, I thought I'd give a run down of the colors and what I went through. I am seriously truthfully an N 0-2 if that existed. My foundations are made for me or I custom blend RCMA. Casper is white, no undertones. If there is undertone, and it's pink, you'll need to find Fawn as it has more pink but these colors aren't covered by TF, not even the Alabaster stick is pale enough, but can be made to work. You can check out Rachel Anise's blog, the BeautyProfessor as she swatches everything and likens them to MAC terms to help out those who can't get to a counter. If you'd like to see my skin color, yes it's real, look up meow cosmetics Snow Lynx and Inquisitive Chartreux. Those two must be mixed for me to match. That's how pale I am. I'm not w/pink undertones, yellow, or neutral, more like without undertones, it exists, but the closet I pull is a very cool olive or blue. I must mix clear, porcelain and KA1 in RCMA to match me. I'm sorry if I was not clear enough but I would not answer if I didn't think I could help. I'm sorry. Please google that site for further accurate information if my personal experience isn't plausible as There are beautiful options in TF, but his colors aren't the same in each formula but that doesn't mean you can't make it work. The contour duos have a lighter side you can use! If you are a pink colored Casper, I highly recommend By Terry Cover Expert in 1 fair, and the By Terry Terrybly Densiliss foundation in 1 & 2 to mix. Cle De Peau B10 is the fairest pink offering they have and that may adjust depending how light you are, the i10 is the lightest but still too dark for me. Koh Gen Do Maifanshi Moisture foundation in 01 is the greatest true very pale pink that blends like a dream, 12 is a bit more beigey but still pink. In their Aqua foundation, you can get 12 and the White highlighter, which has no shimmer and was intended to be mixed with the Awua foundations, to lighten it and that works seamlessly also. Fans I know of the TF Traceless Perfecting are switching to Marc Jacob's reMARCAble serum foundation as it is similar w/ better coverage and dry down. Again I have no match. Some Casper pinks like 10, others can't find one with enough pink that's still pale enough, and then there's MUFE HD. I had no success, others have. If you are looking for a beautiful powder foundation, and you are a Casper Pink, I'd definately suggest to try the new Koh Gen Doh Silky Moist Compact Powder/Foundation in the shade 12. These are also available as swatches on that site I mentioned. Coverage is great. The powder can be used multiple ways and looks great on. Good luck in your search!
I hope that's a bit more helpful with my references.
