Color scaling function

Question

I am trying to visualize some values on a form. They range from 0 to 200 and I would like the ones around 0 be green and turn bright red as they go to 200.

Answer 1

Looking through this wikipedia article I personally would pick a path through a color space, and map the values onto that path.

But that's a straight function. I think you might be better suited to a javascript color chooser you can find with a quick color that will give you the Hex, and you can store the Hex.
