Is it possible to make a hue color scale which can then be converted to RGB?

I have a brain atlas image that is set with hue color values between 0-1 that are then converted to RGB. Different regions of the brain have different hue values based on the inputs of the areas being selected. What I now want to do is creat a hue color scale that goes from cold colors like dark blue to hot read, sort of like a heat map. Would you know how I could do this?
