¿Cómo agregar una tabla de colores a un tiff de una banda usando GDAL?

Tengo un archivo GeoTIFF de 1 banda. La interpretación del color para la banda es gris. Quiero una tabla de colores con el fin de transformar mi Col.tiffa Col.jpego Col.png.

Intenté poner una tabla de colores en este tiff a través de un .vrt:

gdal_translate -of VRT  Col.tiff Col.vrt

luego agregando en el .vrt:

<ColorInterp>Palette</ColorInterp>
<ColorTable>
   <Entry c1="0" c2="0" c3="255" c4="240"/>
   <Entry c1="0" c2="0" c3="254" c4="240"/>
   <Entry c1="0" c2="0" c3="253" c4="240"/>
   <Entry c1="0" c2="0" c3="252" c4="240"/>
</ColorTable>

Y traducir de nuevo:

gdal_translate Col.vrt Col.tiff

Pero respondió:

Warning 1: Unable to export color table to GeoTIFF file.  Color tables can only be written to 1 band or 2 bands Byte or UInt16 GeoTIFF files.

¿Cómo puedo hacerlo?

Para información, hay gdalinfo para la banda:

Band 1 Block=55x18 Type=Float64, ColorInterp=Gray
  Description = Something
  Metadata:
    GRIB_COMMENT=Something[p]
    GRIB_ELEMENT=TMP
    GRIB_FORECAST_SECONDS=0 sec
    GRIB_REF_TIME=1401926400 sec UTC
    GRIB_SHORT_NAME=SMTHG
    GRIB_UNIT=[p]
    GRIB_VALID_TIME=1401926400 sec UTC

con gdal, puede colorear una imagen basada en gdal_dem ( color_relief )

La sintaxis del archivo de configuración de color se deriva de la admitida por la utilidad GRASS r.colors . Los archivos de tabla de colores ESRI HDR (.clr) también coinciden con esa sintaxis. El componente alfa y el soporte de tabulación y coma como separadores son extensiones específicas de GDAL
