MATLAB: How to convert Temperature maps into rgb images

rgb

I am using satellite derived temperature values and I want to convert them to rgb so that I can perform superpixels clustering. I am trying to have the rgb values for each pixel (of the colormap). What do you suggest me to do?

This should work
n = 100;                                         % number of colors
mycolor = jet(n);                                % create a colormap
index = interp1([Tmin Tmax],[1 n],Tcur);         % get index for current temperature
index = round(index);
mycolor(index,:)                                 % color of a pixel
Let me know if it doesn't work
