Beach wedding attire

We recently picked out pants for groomsmen, they’re all matching my groom. I have my stepdad and dad walking me down the aisle and my future father in law is our officiant, so we ordered them pants that match each other. (Dads match). Their pants are true navy blue while the groomsmens are more of a distressed “Royal Navy” color, much lighter but still dark looking. They will all be wearing white shirts. My brother (Irish twin, absolute best friend) is my MAN of honor, and I’m thinking of him wearing pink chino pants (beach wedding casual remember) to match my bridesmaids.. again with a white button up shirt also. I know the dads aren’t technically in the wedding party, but is that too many different pants going on? What do you think? Also, are the dads okay to be tucked in while the groom and groomsmen aren’t? I welcome ALL opinions. Even on questions I didn’t ask. 😂 thank you. Attached is the color of pants for groomsmen.
