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

I only earned about 1 1/4 points per hour over the last month. Only about 40% of my Answers get Accepted. I am getting older and will not be around forever. Someone will catch up some day.

Well Walter, unless you can continue from the afterlife, to stay in the lead you'd better get to work on that AI answerer robot that can answer posts automatically long after you're gone.
