That is nice. The blue is a bit heavy, but that might be my display. Now, how should we order it by default? I am used to thinking of blues as lower values, and reds as higher. The yellow at the end throws me off a bit, because I would think of it as a "weaker" color. Maybe if it was more gold-like? We should also start thinking of a snazzy name. BlRdYe probably won't cut it.
