Change polygon border color

[Mikhail]

Hi All, I want to combine two layers on a map, and outline the polygons in one of them in some colour other than black. When I go to 'Symbology' and then 'Primary Symbology' I see a menu that contains various options for the polygon body colours but no colour options for borders. Yet this looks like a basic task and I guess I am going something wrong. Could anyone help, please?

You permanently join fields using the Join Field tool.

As for you second issue, you say "color looks difficult", what does that mean??? Edit you question, may be a screen shot to explain why you think the colour looks "difficult"?

Thank you, I have indeed asked two separate questions. I have edited my post to focus on my priority: changing the polygon outline color in ArcGIS Pro 3.0.3.
