[Gdal-dev] simplest method for creating/editing a GTiff color table

[Gregory, Matthew]

Sorry for a what is likely a very simple question, but a day of web
searches has left me frustrated ...

I have a simple GeoTiff that has an embedded Color Table with this
gdalinfo:

Driver: GTiff/GeoTIFF
Size is 13354, 7330
....
Band 1 Block=13354x1 Type=Byte, ColorInterp=Palette
  Color Table (RGB with 256 entries)
    0: 0,0,0,255
    1: 254,254,254,255
    ...

What is the easiest way (GDAL or not) to edit this color table?  Or
alternatively, what is the easiest way to create and associate a color
table with a GeoTiff?  Sorry if this has been addressed already.

thanks,
