I got this done today. I am a little behind on pics because I am overhauling my work space. My goal is to have a place set up all the time to take swatch pics. Right now I have to set up and tear down because I usually do the pics in the kitchen.
Anyway, here is the one you requested. IMO Cougar and Wildcat are quite neutral. I was surprised at the amount of purple in Wildcat. Not overly purple, but you can see it IRL. I think Cougar, Wildcat, and Brown Sugar complement each other very well. I will get this up on the forum, too.
