I re-toped a sculpt for the first time ,when I click poly frame on the new topology its all red.
Did I miss a step?
Thanks
Hey there,
don’t know if i understand your problem (if there is any) When you do a retopo the resulting mesh will be one Polygroup, that’s why switching on Polyframe will give you one preview color. If you go to Polygroup/Group visible the color will change … just in case you don’t like the red 
Hope that helps
