Hi friends ,
As I am working on a project and one thing I am trying to create a polygon I insert as a polyon note. It is automically add to ArcGIS Pro as a custom color with light blue and transparent which I like a lot .
It looks like this

Now what I would like to change the color to red polygon as a 75 percent and keep the outline as a black with 0 percent transparent . See example here

I played around the effects here to try to get the red color to be more vivid transparent deep to see through?

Any suggest for that ?
