Ak, I’d check with Kelly Moore. We used their paints in our last (custom) home and had a local store with very knowledgable paint experts. I always knew I was in good hands with them and I much prefer the quality of their paint over SW and BM.

Some of their whites:

Try Alabaster (SW) if White Dove doesnt work. It is slightly beige.

What about BM CRISP LINEN

Jinx and AT, we live in the few states that carry Kelly Moore. it is favored by all the paint pros where I live (SF North Bay).

ETA: KM is also good at matching colors. My fave off white is SW Antique White, all over my house mixed by KM.

SWilliams Dover White, a warm white, also has some gray in it. This hint of gray keeps Dover White from looking too sunny, and helps tone the color down a bit. LRV (Light Reflectance Value) of 83, which indicates that Dover White is very light, will reflect a lot of white, and is just a shade off of a true white.... Try it with medium -dark blue paint colors, green paint colors, red paint colors, and some other more saturated yellows, browns, or grays.

For example, Sherwin Williams pairs Dover White with Waterloo, which is a dark highly saturated bluish green paint color. It also pairs it with Dakota Wheat, which is a golden paint color.

"For trim colors, Dover White needs a very clean bright white to make it stand out. My two top choices are Benjamin Moore Chantilly Lace or Sherwin Williams High Reflective White."

Possibly a bit of pebble/stone natural colors like the vanity and wall color would look good with the bright white mentioned on this website:

Online about Sherwin Williams: "Alabaster doesn’t lean strongly towards any one color, and almost has a greige undertone, which means that it has both a beige and gray base. Without a visual comparison to a real true white, Alabaster will look completely white."

Thank you guys! I think the problem is that the tile and maybe grout have a pinkish undertone.

I have had Dover White painted cabs and I have seen how they can read with a slightly green undertone.

I think Alabaster might work in that it has no real yellow undertones. I was almost thinking she might need a bit of a pink undertone given all of the tile.

First and foremost I want to find an off white with zero green undertones!

I will keep you posted.

My cabinets are similar in color to Kculbers above, and some undertones (esp green) made them look purple. I was using SW paints, and Greek Villa worked the best. I have Alabaster in my primary bedroom and bath, and you almost don't notice it. It's lovely, too.

Has she considered painting the tile? It would eliminate the need to work around that one big factor, and then she could truly go with whatever she likes. How to paint your ceramic tile

What about LINEN WHITE, Ben Moore.

SW Antique White, is what I have all over my house. I had it mixed at Home Depot in their Behr paint. It is a soft antique white with no blue, green, or gray undertones.
