How to make fh stand out among groomsmen?

A navy tux and a floral patterned tie for your FH would look great with your color palette.

For my guy, he'll be wearing a boutonniere version of my bouquet while the groomsmen will have just a white rose.

I didn't even think about switching up the boutonnieres! That's a great idea!

It's kind of in-between sky blue and sage green...like a very light greenish blue

It was all his idea. In his words, "I don't want to be the same as those losers".

My FH has a slightly larger boutonniere, but he's also considering a slightly different tie or adding a pocket square.

My fiance was in the same jacket & pants, but bought his own white button down so we could get it fitted to him perfectly. He wore black cowboy boots, his own black belt, a light blue paisley tie, and an elk antler lapel pin. The groomsmen wore a solid light blue tie and no lapel pin.

I'm glad I wasn't the only one who didn't know "mist" as a color lol.

H wore a bow tie whereas the other GM wore regular ties, and H had a peace rose as his boutonniere, the others had Gerbera daisies (my bouquet was peace roses and Gerberas and my BMs had Gerberas).
