Conditional formatting if cell contains xx

[TimBell]

Hello,

Could someone give me an example how to code a conditional formatting in VBA?

A1 B1 G1
1 2 12


If G1 contains any of the numers given in A1 and B1, then G1 should turn green, if not, then red.
I posted a question like this before, but my explanation was way to complicated. I hope someone could help me this time.
