Whenever I see that red circle and exclamation mark I think "something is wrong or bad." In our culture in many ways red has bad connotation: red light = stop, negative cash in bank account is red, flashing red lights on fire trucks, etc. Green feels more like priority....like "get after this one" or "this one has the best chance of success" and therefore it's a priority, etc. Anyway, just may be the way I think. I'm not everbydody. Just a thought
