I have a function that returns float results in the interval [0.0, 1.0]. I would like to visualize the results using color ranging from red for 0.0 to green for 1.0 (maybe through yellow for 0.5). How could I do that? Thanks!

I think the simplest way is to work in HSL/HSB (hue saturation lightness), where the hue values 0-33% of the maximum will map to the range red-orange-yellow-green. The advantage of working is HSL (vs RGB) is that the resulting color range will be much better-looking (eg bright yellow in RGB contains a pinch of blue).
So basically you will create a value based on a constant S and L value, and a H that corresponds to
and then transform that value back to RGB for display. Don’t know Python (shame on me) but apparently the colorsys module can do this transformation for you.
