I have a similar problem. I moved into a home with Taj Mahal quartzite, need to paint cabinets and picked white dove but want to have accent color on the island. My backsplash is an ivory glass tile which looks pretty minty green. Any moody blue to try and bring some blue into the room? I was looking at trout gray or wolf gray. Will this look terrible? Also I’m thinking satin bronze pulls to bring out the gold in the Taj Mahal.

Floorplan is helpful, but we also need to know how wide your aisles are currently (they look tight around the island?). Here's a quick idea (may not be feasible depending on aisle width) - it might look a little odd to leave that arch hanging but it would give you seating and remove the current barrier island. With the new opening to the LR, you could possibly close off that doorway next to the fridge (where does it go?) and/or partially close the opening between kitchen and breakfast (could be used for pantry space, etc. if necessary). I squared off the angled pantry but I was guessing at the measurements. You could leave the angle as-is with this layout, but the overall appliance arrangement can probably be improved by eliminating that angle (depending on those exact measurements). Or a similar idea with an island instead of peninsula, with the sink and DW moved to the perimeter:

My husband and I have chosen Taj Mahal quartzite for our kitchen counters. I know it looks gorgeous with white but we would rather have some sort of color. I’m not totally against white cabinets with a different color on the island. I found these pics on another thread but there are no answers as to paint color. I like SW Snowbound as the trim color in our house (and would be cabinet color if we go that route). I’m hoping someone has an idea/suggestion of what grays are used in these pics. Any help and/or suggestions you can offer would be greatly appreciated.

Did you physically see the slab? If so, go back and ask them to pull it again and take a photo of the bar code sticker on the end side of the slab. That has all the unique identification numbers. Take a photo of the whole slab as well. Take a cabinet door (if you have it or any other element samples you have) with you and get a rep to hold them up while you take a photo of the slab. This gives you proof of your purchase, so you get the slab you ordered and paid for! I have done this many, many times and mentioned it here on Houzz several times as well. Good luck!
