Why gray? I need pics of the choices you have already made to offer help. Post the pics here in a comment DO NOT start another post .

Thank you, I chose gray because I still have a lot of wood trim and thought gray worked.
The main cabinet colours are Chantilly lace white and cinder grey for the island. The quartz colour for the island is frozen tundra. I’m trying to decide on a colour of gray for the main countertops (either cinder grey or grey expo).

This is the flooring

The less gray the better.

I don't mind gray on principle, but your other finishes are quite a bit warmer in tone than that icy white/gray quartz. I hope that you have samples of all of them to put together in the same room -- photos are no substitute!

I agree your samples look much warmer than cool quartz.
