Choose the outline color for all shapes within this shape layer. You can pick a color using the Power BI color picker or enter a custom Hex or RGB value by pressing the More colors button.

Outline Color customization is available if your selected Shape Layer Type is Built-in Shapes, Geo JSON, or Node Reach. This setting is not available for KML shape layers as their formatting rules are governed by the KML style file (unless Style Override is used).
