I've never found any way to convert from temperature to color, but something you
could try is creating an array of an arbitrary size, and then fill it with color
vectors taken from your gradient using eval_pigment.

once you have the array filled you can grab the color from your array by passing
it an index.

if your gradient is an image you can turn it into a pigment by using an image
map and scaling it appropriately.
