This is a real basic question, but I can't seem to find it. How do I add a color ramp in QGIS? I noticed that has different applications you can add to QGIS (like RdYlGn, GnYlRd, cpt-city, etc...) but I didn't find those in the plug-ins manager window. Could someone explain what are the main difference between those and How to install these add-ons?
I am using 2.14.0 on Windows 10.
