[gdal-dev] Change color to TIF file with GDAL

[AlonMF]

Hello everyone
I have a tif file named ndvi.tif that contains values between 1 and 1. The
file is with one band.
In addition, I have a ndvi.vrt file which I am trying to edit.
My goal is to change the color of the image according to green-orange color
values. Currently the picture is black and white

I run the command:
gdal_translate -of GTiff -ot Float32 C:\Users\oze\test.vrt
C:\Users\oze\modified_palette.tif -scale -1 1

The resulting output is between 69 and 241 and the colors are still in black
and white rather than green-orange as I requested.

This is test.vrt file:

That's how it looks before everything:
<http://osgeo-org.1560.x6.nabble.com/file/t384615/aaaa.jpg> 


This is how it looks after the command is run:
<http://osgeo-org.1560.x6.nabble.com/file/t384615/bbbbbbbbb.jpg> 

It's important to me that the colors look like this:
<http://osgeo-org.1560.x6.nabble.com/file/t384615/ccccccccc.jpg> 


These are the values before:
<http://osgeo-org.1560.x6.nabble.com/file/t384615/ddddddddd.jpg> 


These are the values after:
<http://osgeo-org.1560.x6.nabble.com/file/t384615/zzzzzzzzzzz.jpg> 


That's what it's important for me to see:

Thanks to everyone who has read and wants to help
