You cannot add to measures/dimensions to the color pane. Only one.
Another way to distinguish the two would be to use either shape, or size.
But this seems like it could be solved using custom tooltips. That way when a user hovers over a county it'll show each category and the number that corresponds to that category
Hope this helps!
Thank you for using Tableau! I found a similar question that I think will answer yours. Please see the link below for more information. Also, if you send a sample workbook I can give you specific instructions.
Essentially, you can drag your first filter onto color. Then drag your second filter to the marks card. Then click just to the left of that filter and select "color". This will adjust the shades of color based on the second filter.

Hi Matthew ,
