Where is the Gray Owl paint sample? Or is it a tile - the one next to the Carrara Mare tile? If it is that medium gray tile, I don’t think it matches well. The floor tile in dark gray, done in a herringbone, is giving me deep blue tones. The medium gray wall tile is giving a greige look.

The Etherial Haze countertop does not really look like it has a similar undertone to the Carrara Mare, either - but that could be a because they are in different photos. Be very carefull of undertones and choosing something that is ”close, but no cigar.” When you have two similar surfaces such as your counter and your Carrara Mare tile, being just off a bit is terrible. It is better to have one a far deeper or far lighter tone of a color with the same undertone family. You don’t want to mix a blue undertone that feels cold (herringbone tile) with a beiger/greige warm undertone. There will be a clash.

That is my non-professional opinion. But I am very sensitve to colors that are just ”off.” I may not have the right terminology, but I have the hairs on the back of my neck stand up and tell me when there is a clash.

Hi Nancy- I have probably screwed up but this is what I have now- the grey tile next to the carerra is the niche trim and ledge- or I could just use the same wall tile for the ledge and use schlueter for the trim- the vanity top is opposite wall to the Carrera wall tile surrounding tub, we were thinking it was close enough but I think photos lie- there is a warm vibe with the vanity and wall tile, and I see what you mean when you say blue undertone if the herringbone but that’s done deal- so do you think a smoky blue wall paint could work? Or go with griege? Thanks for your time

Here’s another pic of tub wall tiles and vanity with quartz top and charcoal floor tile

I would skip the small gray tile.

Look at the Kylie M interiors blog, she covers a lot of gray options! https://www.kylieminteriors.ca/what-are-the-best-true-gray-paint-colors-with-no-undertones/

she describes Gray Owl as fairly neutral with blue-green undertones.
