Read the image. mat2gray() to convert it to the range 0 to 1. im2uint8(). ind2rgb() passing in a colormap with 256 entries. The result will be an RGB image created by doing pseudocolor lookup on the grayscale image.

cmap = copper(256);
recolored_image = ind2rgb(IndexedImage, cmap);

A short search in the internet (meta message :-) ) reveals this:

cmap = copper(256);
numslice = size(IndexedMHA,3);
colored_MHA = zeros(size(IndexedMHA, 1), size(IndexedMHA, 2), 3, numslice);
for slice = 1 : numslice
colored_MHA(:,:,slice) = ind2rgb(IndexedMHA(:,:,slice), cmap);
end
Note: I put the color data as the third dimension. Some of the File Exchange routines work with the color data in the third dimension but some work with it in the fourth dimension.
