[gdal-dev] Incorrect "land cover" color from USGS GeoPDF

[John W. Glendening]

Using gdal_translate to extract the non-image, non-border map from a USGS GeoPDF

  gdal_translate CA_Lopez_Point_OE_W_20120306_TM_geo.pdf o36121a6.tif --config GDAL_PDF_LAYERS_OFF "Map_Collar","Map_Frame.Projection_and_Grids","Images"

I find that while the colors of the contour lines and text match those
seen when viewing the file with the Adobe reader, the "Land_Cover"
layer comes out gray instead of green (per the Adobe reader).  Can't
find any info regarding this so decided to ask here.  FYI the input
file is available at
 http://bigsurtrailmap.net/TEMP/CA_Lopez_Point_OE_W_20120306_TM_geo.pdf
I am running GDAL 1.11.0 compiled on a Ubuntu 14.04 machine.
