Random question about range bands

So after playing a few games a random-ish question came up. Why didn’t you make the range bands follow the color/rainbow spectrum order? Red-Orange-Yellow-Green-Blue-Black? It would have made them a lot easier to remember.
Also, some kind of master weapons reference sheet would be helpful, that way we wouldn’t have to pass a card back and forth, or search thru our stacks in order to find the one we are looking for.
