Blue...
I use Boris Wilds a lot, and blue makes a difference... and sometimes I do a chicago opener, so the red really stands out! Plus, I think that being darker backed, the audiences attention is more on the faces of the cards, and if there should be an unwanted flash of a card from between my fingers, if it's blue it'll stand out less than red.
