Thanks a lot for your help!
Have you tried simply growing it longer, perhaps it grows slower in the YPEG?
I have noticed when plating these things that on YPD sometimes it takes a bit of time for the red color to develop on the colonies.
Right now we are growing basically the exact same thing, W303 in YPEG, and they definitely are red.
