Can someone help with a possible ID?

Hello!

So, my new tank is in the uglies! I'll start off by saying, I have no intentions of any drastic measures for this algaes removal besides basic husbandry because the tank is so new, started with dry rock (1 1/2 months)

Could I get an ID on this algae?
It appears green when removed, so I'm inclined to believe its a GHA, but its heavily brown/gold under my reef lighting (no greens).

Yes, it's GHA. If there is no green light from your lighting, then it can't reflect the green that we normally associate with it and the coloration will be different.
