2. For 'Color', use the drop-down menu to select Mango.
   
   
   
   
3. For 'Outline color', use the drop-down menu to select Gray 50%.
4. At the bottom of the Symbology pane, click Apply.
5. Access a shortcut to color properties by right-clicking on the Wastewater_Outfalls point symbol. Select Mars Red.

The super neighborhood polygons are now easy to distinguish from both the basemap and the rivers. In addition, the borders of the super neighborhoods are clear and easy to differentiate from the freewayswhile the wastewater outfalls are highly visible in red.
