How to color all map points in a single color

If you upload data to the Points layer in the Projection map template, the automatic column binding feature may select a categorical column to color your points by. This means that different points will have a different color assigned. To make your points a single color:

Go to the Data > Points tab and check if there is a column bound to the Color by setting.  

To color all points in one default color, leave the Color by option blank. You'll see the result in the preview window immediately.

Your colors should now all appear in the same color. To change their appearance, head to the Preview tab > Points layer and adjust the relevant settings. 

That's it! To learn more about points customization, check this help doc.
