Whimsical Designs for Rug Hooking
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 softer and warmer than grey.
