Perfect foundation

So I have been noticing lately in a couple of big block buster films that they are having trouble with the foundation.  Here is something that I figured out early on about foundation.  If you have a red complexion, it will be difficult for you to find a foundation that is a perfect fit.  Let's face it, it is difficult for most of us to find a perfect fit straight off the shelf.  Find another colour that is red-ish and add a little bit to the one that is the closest fit to your shade.  This way you can knock down the red without completely trying to eradicate it.  If you did knock out the red completely, you would look like you were wearing a mask and it wouldn't match your neck or decolletage at all.
