color scale to illustrate the temperature, Python script

I make an astronomical visualization, which illustrates a birth of a planet from a cloud of particles (which i have over 130.000). Each particle, besides xyz-coordinate, has also a temperature value.

Is it possible to code it like Temperature minimum is green, Temperature maximum is magenta. Dear script, color my particles in scale between green and magenta?

I am working with Python (Blender).

Thank you in advance for any help!

Solution

Not familiar with Blender, but assuming you can assign RGB values, this loop will fade from green to magenta:

counter = 130000        # number of particles in your cloud
change = 256 / counter  # in-/de-crement for each particle

rgb = [0, 255, 0]       # starting colour (green)

for i in range(0, counter):
    rgb = [rgb[0] + change, rgb[1] - change, rgb[2] + change]
    print("i: %04d; R: %03d, G: %03d, B: %03d" % (i, rgb[0], rgb[1], rgb[2])) # for debugging only, floats to integers for legibility

There's probably more sophisticated solutions, but hopefully that'll get you started.
