First, confirm your ENVI Classification file is indeed what you think
it is by looking in the header file. Then, use ENVI_FILE_QUERY to
retrieve LOOKUP and CLASS_NAMES. LOOKUP provides a [3,num_classes]
array of color triplets for each class. You can then apply that by
loading it into the color table to display the data from
ENVI_GET_DATA.
