I would bring a sample of the tile to the store and see what matches. Your cabinets seem like a optical white so maybe a light cool white or silver gray. The current color is not it, though.

Benjamin Moore Olympic Mountain - or - Farrow Ball Shaded White - both are lovely.

I spent a lot of time researching this last year, so I understand your delimina here. You will be safe with either of these colors! They both are light, airy, provide contrast, blend well with other neutrals (greys, white beige). and change based on the light. Your kitchen is lovely. Have fun!

a lot of dark shadows up at the ceiling..no windows...not all that much ceiling lighting...I would get a creamy white for the walls. Stay with white: find one that works with white cabinets.....not any grey.

your feedback and guidance are greatly appreciated!! You have helped us narrow down on the colors. THANK YOU!!!
