So far, QGIS does not come with many default symbols. Quite often one just needs two or three colors that go well together. That’s why I created a series of simple fill symbols based on ColorBrewer. They are available on Github QGIS-resources:
- 7 diverging classes: https://raw.github.com/anitagraser/QGIS-resources/master/symbols/colorbrewer_polygon_diverging_7classes.xml
- 5 sequential classes: https://raw.github.com/anitagraser/QGIS-resources/master/symbols/colorbrewer_polygon_sequential_5classes.xml
As always, these XMLs can be imported using Style Manager.
