Do want us to look up all those elements? and should we imagine what the room looks like? please try and understand this from our viewpoint. we have no idea what your kitchen looks like, what kind of lighting you get, what 'brown/gray' hardwood looks like, or a gray ceramic (there are literally 1000 shades of gray) you want to use. Imagine you're us and have never seen any of this. Now imagine us trying to give you the best advice. we're blindfolded here throwing darts at a board.

help us help you.

You'll get better answers if you make things easier for people to comment. if all of us have to look up that color and that countertop, and then try to imagine what a brown/gray looks like, you're going to get limited help.

post pictures of every single item youre getting and every view of your kitchen that you've mentioned

I couldn't help myself, and looked up your paint/countertop

I've never heard of "Five Star" do you mean this one?

I went and looked up Lusso. yes the colors seem to go. however, that's a lot of gray. gray cabs, gray floor, repose gray for the walls. man. do you have an island?

This wall color is Crushed Ice, and it's one click down from First Star. similar tones. you'll notice it's more of a platinum gray. more silver. So stay away from blue/gray tiles.

I think doing the First Star on the walls w/White cabs would be a better option. otherwise, you'll have a gray overload. if you're doing an island, I'd consider a natural white oak just to get some warmth in there w/all those gray tones
