I used Swiss Coffee on my stucco and it's actually pretty white. not blinding white, just a nice white.

If you're using a taupe, you don'w want a yellow white.

Try some of these and bring home samples

Eider White Or Pearly White might look nice w/the taupe. but you can't go wrong with BM Simply White.

Benjamin Moore White Dove. Its a perfect exterior white for what you’re describing. It’s a soft clean white that’s not too warm and not too stark it falls right in the middle and looks beautiful no matter what it’s paired with. My personal favorite white is Benjamin Moore Chantilly Lace it’s a gorgeous bright white with zero undertones neither cold or warm. It’s my perfect white. For a warmer color, Benjamin Moore Swiss Coffee at 75% is another stunning choice. A link with paint colors: https://studio-mcgee.com/the-mcgee-home-paint-schedule/

Egret white is what we used for the trim and it’s a beautiful warm white.
