Hi Frank,
here is how I modify the vrt file:
<VRTDataset rasterXSize="1200" rasterYSize="1096">
  
<SRS>GEOGCS[&quot;NAD83&quot;,DATUM[&quot;North_American_Datum_1983&quot;,SPHEROID[&quot;GRS

  <GeoTransform> -1.2459079918952935e+02,  8.9964705882352915e-03,

  <Metadata>
    <MDI key="AREA_OR_POINT">Area</MDI>
  </Metadata>
  <VRTRasterBand dataType="Byte" band="1">

    <NoDataValue>-3.40282346638529E+38</NoDataValue>
    <ColorInterp>Palette</ColorInterp>
     <ColorTable>
       <Entry c1="255" c2="255" c3="255" c4="255"/>
       <Entry c1="0" c2="0" c3="0" c4="255"/>
       <Entry c1="35" c2="66" c3="55" c4="77"/> 
     </ColorTable> 
    <ComplexSource>
      <SourceFilename relativeToVRT="1">GoesWest1V1561915.tiff</SourceFilename>
      <SourceBand>1</SourceBand>
      <SrcRect xOff="0" yOff="0" xSize="1200" ySize="1096"/>
      <DstRect xOff="0" yOff="0" xSize="1200" ySize="1096"/>
      <ScaleOffset>0</ScaleOffset>
      <ScaleRatio>2559.99</ScaleRatio>
    </ComplexSource>
  </VRTRasterBand>
</VRTDataset>


Yes I have tried to import the vrt file into GE but the same thing it showed in 
gray scale, also I tried to convert the modify VRT file back to geotiff but the 
same thing (gray scale). 

thanks


Hi,

After modifying the VRT file to include a color table (why didn't you
show us that VRT file!) what did you do?  Did you try to open the VRT
in GE?  Did you gdal_translate that VRT back to a new geotiff and try to
view that?    Can you expand on "but that doesn't work"?

Best regards,
