This is not true. The docs make it very clear that the index numbers are 
used in for instance a .gif file.

Quote:
    "The color of the palette entry does not affect the height of the
     pixel. Color entry 0 could be red, blue, black or orange but the 
     height of any pixel that uses color entry 0 will always be 0. Color
     entry 255 could be indigo, hot pink, white or sky blue but the 
     height of any pixel that uses color entry 255 will always be 1."
