Tie color question. Need advice!

Our colors are navy, pale peach, gold and ivory. The BMs dresses are navy and the GMs suits are gray, white shirt and pale peach tie. I have one "bridesmate" who will be wearing the same suit/white shirt as the groomsmen but with a navy tie to match the BMs. What color tie should my FH wear with his gray suit? My dress is champagne and ivory so I was considering a champagne or ivory tie. Is that too many tie colors for one wedding party? Another possibility is to have my bridesmate wear the same pale peach tie and have my FH wear a navy tie. Too many options!! I need advice.
