device, decomposed=0

From the IDL online help:

Set this keyword to 0 to cause the least-significant 8 bits of the color index value to be interpreted as a PseudoColor index. This setting allows users with DirectColor and TrueColor displays to use IDL programs written for standard, PseudoColor displays
without modification.

Set this keyword to 1 to cause color indices to be interpreted as 3, 8-bit color indices where the least-significant 8 bits contain the red value, the next 8 bits contain the green value, and the most-significant 8 bits contain the blue value. This is the
way IDL has always interpreted pixels when using visual classes with decomposed color.

Best regards
Kevin
