It's hard to tell on my computer, but the wall color looks like a cool grey, the shower tiles look like a warm grey with sort of purplish undertones, and even the "stark white" on the cabinetry/trim/doors looks like a warm white, especially in contrast with the cool-toned carrara vanity top. Is that correct? And what sort of natural light do you get in the room -- north facing, south facing, etc?

I think, taking into account the natural light, you need to find shades of grey and white that will work with the existing tiles and with the marble vanity top.

Thank you! The cabinets have not been painted yet. This is the existing White which has yellowed significantly over time (or maybe was always off white. I was planning on doing a stark white on the cabinets... painting is on hold while I decide if I want to stick with this wall color.
