Okay. Radical suggestion about how to think about OP's core issue. Ready? There are actually very paint colors that are "gray". Like, out of 30 + paint brands I can count them on one hand. All the rest of the colors that people refer to as gray, aren't really gray. They are colors that have been moved off, knocked back from full intensity to the point that they are closer to - or resemble more - a true neutral gray than they do a color like green, purple, blue, etc. And I think that's where people get confused. Gray doesn't have a green, purple, blue, red, etc. undertone. "Gray" for gads sake can't have an undertone because of this little annoying factor called achromatic - gray isn't a color. I understand where that logic comes from. If we label colors "neutral" they suddenly sound more friendly and imaginary-i-ly adaptable. Imaginary because all the colors labeled as *neutral* 99.9% of the time don't end up "going with everything" like we've be programmed to think a neutral color should. It's this vicious circle of twisted color thinking and there are so many people who are holding on for dear life that the thing just keeps spinning and spinning and spinning from its own centrifugal confusion. "Cuz if there are THAT many people on board with this way thinking about *neutrals*, then it must have started from somewhere, really, really, really good. But no one questions what that original source might have been. They're just hanging on because, well, lots of other people are too. Darndest thing ever. If you use a true gray wall color, it's going to go with everything. In a three-dimensional architectural context a gray wall will appear to take on complementary characteristics and it blends. Gray doesn't necessarily go with everything, it just doesn't NOT go with everything. It'll be tough to prove me wrong on this one because no one actually picks a true gray paint - so who's to say if this is right or not? When people think their khaki paint colors clash with their beiges it's not because those *neutrals* don't go together. It's not because they don't have the "same undertone". It's because fundamental color harmony is lacking between the two architectural paint colors and odds are the same fundamental color harmony would be lacking between those two architectural paint colors at every increment from most neutralized all the way up to full intensity. They just don't go together, they have clunky levels of contrasts, ideally pleasing color harmony just isn't there. Peel this all back and, yes, finding warm and cool neutrals for adjoining rooms that will harmonize is quite the task. I mean, shewt, first have to figure out how to see the undertones, then you have to hold your tongue and recite the alphabet, and then you have to hop on one leg and sing the Star Spangled Banner, and on and on. Where as finding a warm color and a cool color for adjoining rooms that harmonize is as simple as falling off a log. People in all walks of artistic professions do that every day.

Also, I used a product called Samplize when I was testing paint colors that was amazing. And more efficient than buying all the little sample size paints to test a swatch. If you sign up for email, you get a $5 off coupon. And you can move the samples to different walls and compare at different times of day. I found this very helpful. https://samplize.com/

Accessible beige has a green undertone, but it’s unlikely it will appear unless it is against other elements that have heavy red or orange Tones. for a warm color you’re trying to achieve you must choose a warm color that You can live with, even if it’s just a tinge, there’s no color out there without an undertone unless it’s white or black. I’d suggest a green undertone neutral to coordinate with your yellow permanent fixtures like flooring, and you won’t necessarily see the green. Plus colors change throughout the day, it’s best to pick a color for each room that looks best during the time of day you use it the most. What about using a wallpaper to make a statement accent wall? Or a wood accent wall with picture frame moulding or shiplap/beadboard, gallery wall with a creamy ultra light white. good luck to you.

I have a sample of Edgecomb on the way... I was thinking if it’s not deep enough, I could see what an extra 50% looked like, thanks!
