I’m a realtor and I employ an interior designer that helps sellers improve their home and up the equity. Gray was huge in 2000-2003 or so. Because people relate gray with Covid it’s now out. Soft whites with bright white trim is an easy sale I can assure you.
Our data center just repainted all of the halls and public areas with off-white, replacing grey. I hate grey walls, and when we were house hunting last year that’s all we saw. White is much, much better. And easy to paint over if you have other ideas. (My wife painted our grey kitchen light green)
This could be a great color to help sellers...
When I was flipping houses in the 90’s, I painted everything with a shade called ‘Milkweed’ from Hallman-Lindsay paints.
And, you are correct. A soft white/cream was always a good choice.
I hated the gray-everything years. Ugh!
