Symbolizing Layers with a Single Symbol
It is early in the project to be deciding upon symbology, however, when layers are added to a map, ArcGIS Pro assigns then a random color symbol. Sometimes the colors are very faint and difficult to see on top of the basemap or the colors of multiple layers are very similar to each other and difficult to distinguish. To ensure that everyone can easily see the layers we are working with, we will adjust the basic symbology.
...
- In the Contents pane, right-click the Major_Rivers layer name and select Symbology to open the Symbology pane on the right.

Notice that the 'Primary symbology' defaults to Single Symbol. With this type of symbology, all features in that particular layer will be assigned the same symbol.

- Within Format Line Symbol mode, click the Properties tab.
- For 'Color', use the drop-down menu to select Cretan Blue.
- At the bottom of the Symbology pane, click Apply.

The rivers on the map should now all be black and easily visible on top of the basemap. The Format Symbol mode of the Symbology tab can be accessed directly via the layer symbol (instead of the layer name) in the Contents pane.
