We are in the high 90s, but it's so dry you don't feel it if you're in the shade.

Go live there, the grass is really a shade brown.

Thanks @Mike D'ArrigoA little more background -- I'm closing on the home in a couple weeks, and the hail damage occurred years ago (the current homeowners claim the roof is 5 years old, but there's a strange strip of shingles that are significantly darker than the others).

Since I've taken over, they send me "demand emails" for silly things like the sprinklers pointing in the wrong direction (which can be adjusted when and if they see this/ and could be from their dogs or children), emergency texts  - requests for ME to  pay the "excessive water usage" charge on their water bill -  in Vegas, now unavoidable for homes that haven't yet been converted to desert landscaping, and the latest one - "have your landscaper address the mushroom growth" problem, which just sprouted up due to heavy rains and the property being in the shade. 

I imagine for the dark(er) sky setting

Though not all shades of taupe are created equal and some can contain a pinkish cast if it's rose, mauve or deep taupe for example. 

It’s a completely different color than the sample that was shown to me (basically the sample showed only one shade of many, and so I was expecting just a dark brown, yet the end result is many different shades that create a very chaotic, wild and jarring look).

I spent many, many hours and a fair amount of money experimenting with paint colors to find a greige shade I really like, that works nicely in most spaces.

Our house stays cool from shade trees. 

We use lighter shades such as Popular Gray and Eider White, by Sherwin Williams.
