What colour suits for the boys in the bridal party?

We have 2 bridesmaids wearing pale ‘cornflower’ blue for a modern boho beach wedding, we have 4 groomsmen and the groom wants a blue suit but I don’t know what kind of blue, and if it will clash with the girls dressed.. I think a clean white shirt would be best, but don’t know what colour ties. The flowers r natives pinks grey and green.
