Question about the colors

[jebowe3]

You just need to determine a range of elevations that encompasses your DEM data. In this case, all of the raster values fall between 3590 meters and 8890 meters. The color range is expressed as RGB values from rgb (68, 1, 84) at 3590 meters to rgb (253, 231, 37) at 8890 meters. Each included meter is assigned a color within this RGB range. This is simply a two-entry version of the techniques for hypsometric tinting presented on websites like Bjørn Sandvik's "Creating color relief and slope shading with gdaldem" and Robert Simmon's "A Gentle Introduction to GDAL Part 5: Shaded Relief."
