As others suggest - you need to try a brand that makes the correct shade for you. Remember that cosmetic companies do NOT stock shades to match every skintone out there - they want to provide as few shades as possible to cover the majority of their customers, because that's what's most profitable. So - your best bet is to try a brand that specialises in providing a very wide range of shades - my suggestions would be Bobbi Brown and Illamasqua. If you visit a counter they can try it on you, and more importantly, give you a small sample to take home so you can be sure you have the right product. (Most counters are happy to do that if you bring along a small container). If you're having to thin down the formula or cover your neck in foundation then you have the wrong shade!!
