I only want to get one Graftobian super HD foundation palette right now, from what I've gathered the "warm" palette works on the majority of people. But just in case I run across a very cool tone client, and the "warm" looks very off on their undertones I was thinking of using the mehron liquid makeup in "blue" and "pink" as color adjusters to drop into the foundation. The price on the mehron liquid is really fantastic which is why i'm leaning towards using them, but what do you guys think? Do any of you have the mehron liquid makeup?
Edit: After looking into it more, the mehron doesn't seem like a good option. What are some good color adjusters to make the warm foundation neutral or more cool?
