I recently read that if you have undertones that look almost yellow-green, chances are you're neutral.
I was told this as well by the company I buy my mineral foundation from, so I got a neutral shade this time.
It blends in with my neck so that I can't tell where I put it on!
With mineral makeup I can wear a warm or cool shade but the neutral one just disappears. If I had a good match before, this is a perfect match.
Thought I'd make a post about it because I haven't seen this info about the yellow-green undertones before...
