As you see in this picture which I've captured in MATLAB, there are two colors.

  • Red with the RGB code (255,0,0)
  • Brown with the RGB code (138,139,1)

enter image description here

I've tried to show the same picture in ENVI, but as you see the RGB codes (255,0,0) and (138,139,0) both appear as red in ENVI.

Does anyone know why this occurs and what should I do to fix it?
