The colormap represents a vector that has 3 elements (red, green, blue) for each luminance level from the image.
ie. colormap[i]=(255, 0, 0) would mean that level i is pure red. i is between 0 and 255.

11 colormaps are implemented in the program and can be changed anytime for the user's taste.

Only the look of the image is influenced by this function. The temperatures stay the same whatever colormap is used.
