You are right,

this is a small example.
create a runtime sav file 'cbar_true.sav' in true color mode of your graphics
card
Then execute the file. You' ll see only greyscaled colors.
If you change to 8bit color mode and you execute again you see a red to white
colorsystem

pro cbar_true
loadct,3
cbar
wait,20
end
