Wouldn't a spectrum make more sense?

The people over at Pop Sugar have put together a little cheat sheet for the new fall television season. They have compiled a chart of the TV bloggers' rankings for many of the new shows. However, this chart has a major problem. A score of 1 is considered very bad, while a score of 5 is considered excellent. To see the chart in its full glory, click here.

Not to look a gift horse in the mouth, but the color-coding makes no sense. A show receiving a 1 gets a green-blue box, while a show receiving a 4 gets a blue-green box (and a show that a reviewer hasn't watched gets a regular green box). A 5 is an orange box, and a 2 is a red box. A 3 is a purple box.

Wouldn't it have made more sense to make a 1 blue-green, a 2 green-blue, a 3 purple, a 4 orange and a 5 red? Or used some other colors, but had the rankings follow along a typical ROYGBIV spectrum? So that when you looked at the chart, the general colors you saw would tell you whether a show was good or bad?

All this just tells me that I need to see Bailey's television preview as soon as possible.

Oh, and how could someone give Big Shots a five? Maybe they lost their scoring key and thought a 5 was really, really bad? Because you know how I felt about it.
