Squirrel Taupe is useful and a good choice to have in your stash. It has subtle movement and values. Another not on the Ives Color Wheel. It's a taupe with a greenish cast to it. Perhaps stones with moss.I've used it for a squirrel and it worked well. It's warmer than grey. To get a suggestion of the color check out Orange Yellow tones 23-21,23-22 and 23-23.
