Of course one end Is getting a cold/blue natural light and the south is getting a warm/yellow natural light. My living/dining room is north to south with south getting a lot of light from a wall of glass and reflection from the pool.

I chose B.M. Ice Formations and think it gets as close as you could get. You know other colors in the space will influence the wall color, and my room has white, gray, soft gold with a off white floor. So, nothing strong like a red or a deep green.

I am looking at both ends of the room right now…3:30 EST and the walls look darn good….as good as it looked this morning.

My trim is B.M Super White semi-gloss , and ceiling the same in flat finish

If you open the Behr Crisp Linen webpage and scroll down, it shows lighter and darker colors. Weathered White is ever so slightly lighter and bluer than Crisp Linen. Perhaps you could paint the north-facing walls Crisp Linen and the south-facing walls Weathered White while not having the difference in paint colors noticeable when the room was lit via artificial light.

On my monitor Behr Weathered White looks like a slightly lighter version of BM Ice Formations mentioned above.

Thank you to both. Can’t wait to go get some of those color samples and test them out :) I appreciate it a lot!
