I have a "QGIS Generated Color Map Export File" in .txt format. I'm trying to load it using QGIS 2.18 but the only file extension QGIS will accept is .qml file format. This question relates what I'm trying to do but provides no explanation as to how to load a non-qml file.
The file I'm trying to utilize is located here: http://www.warrenpinnacle.com/prof/SLAMM/GCPLCC/slamm_colors_qgis.txt
