This question already has an answer here:
I have download the following Landsat 7 image
I want to open a true color RGB composition using bands 1, 2 and 3. For that, I import the Tiff files of the bands. When a create the RGB composition (raster, miscellaneous, virtual raster) the result does not look very nice. My issue is not that the image is dark (there is a lot of ice/snow) but that the true colors are not very accurate. Water looks purple, glaciers have some purple areas, etc. Am I missing something to create a good looking true color RGB?
The output should look like this
