according to the BM website for white dove,

there are 4 "similar colors" Oxford white, steam, vanilla milkshake, and Swiss Coffee.

Although, maybe you want to take something from the Summer Shower pallet. Patriotic White might achieve what you are going for.

Thanks! The patriotic white chip looks too blue to me. I have seen Swiss coffee recommended a few places as a versatile white.

Maybe simply white?

i used BM steam for one of my bath ceilings. it has grey undertones, goes well with my super light green (BM linnean grey). i think it would match white dove pretty well.

agree it does on the computer, but these off white colors tend to look white IRL. Also you could get it mixed 20-30% lighter just to be safe and to be sure you don't pick up unwanted other undertones.
