Create a way to change a feature's color to another color from the selected color palette / color scheme when using Unique Values symbology.
I am working with a polygon feature class and using Unique Values to make each polygon visually distinct, like on classic political maps where each country is a different color. I'm using the "pastel" color scheme. But in some cases, there are so many polygons adjacent to each other (very odd sizes and shapes) that some adjacent polygons are just about the same color. I have to go through and manually change the color of some polygons to make the colors more distinct. It is frustrating that I can only pick colors from the standard ArcGIS color picker, or else create custom colors via RGB, HSV, etc., and I cannot pick from the "pastel" color scheme I selected for the layer's symbology. This is making the layer's symbology look pretty random and unprofessional.
It would be a giant help to be able to change a feature's color to another color from the color palette I chose for the layer.
