How to add a color table to a one band tiff using GDAL?
with gdal, you can color an image based on gdal_dem (color_relief)
the syntax of the color configuration file is derived from the one supported by GRASS r.colors utility. ESRI HDR color table files (.clr) also match that syntax. The alpha component and the support of tab and comma as separators are GDAL specific extensions
