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:
1
Go to the Data > Points tab and check if there is a column bound to the Color by setting.

2
To color all points in one default color, leave the Color by option blank. You'll see the result in the preview window immediately.

3
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.

4
That's it! To learn more about points customization, check this help doc.
