You don't give much information.
You probably want some steps like this, assuming you have a byte
intensity map called MAP.
device, decomposed=0 ;; Use color table mode
loadct, 14 ;; Pick the color table you wish, 14 is an example
tv, map ;; Display the image with the color table you chose
If you have a non-byte map, then you will want to use TVSCL. There
are better procedures for making labeled images like TVIMAGE,
PLOTIMAGE, or IMDISP, which you can try when you understand color
better.
Good luck,
Craig
