No, that's not the beauty of it at all. In fact, I find it rather ugly, ignorant, and damn near caveman thinking style.
If I was to vote, it wouldn't be on a simple color, it would be on each candidates' values and goals. Sadly I can't remember every last candidate, so I do not consider myself a well educated potential voter.
But hey, if folks wanna keep voting on simple colors, well my favorite color is blue. So if it's so simple, why can't I just pick up a blue card, write my name and voter info on it, and just submit that?
