Darre,

With GDAL "trunk" the following seems to do the trick, and could
be easily extended to loop over many files.


import gdal


def update_ct( file ):

     ds = gdal.Open( file, gdal.GA_Update )

     ct = ds.GetRasterBand(1).GetRasterColorTable()

     ct.SetColorEntry( 123, (255,255,255) )

     ds.GetRasterBand(1).SetRasterColorTable( ct )

     ds = None



update_ct( 'test.tif' )


Best regards,
