Symbolising Information
-To change the symbology of a layer (such as changing its colours, lines, fills) , open the Layer Properties dialog by double clicking on the layer name or by right-clicking on the name in the legend and choosing Properties and then choose Style from the left side of the properties window.
(Note: To see a video tutorial on QGIS symbology tools, please refer to QGIS 3 – Symbology. The tutorial is for an older version of QGIS, but the same principles apply.)
