Hello all. I am trying to create my own color scheme for unique values but I want to set the custom color to predefined unique values so that every time I upload data to the map and use this scheme I will get the same colors for those values. Example.

I am uploading points which all have a "Color" column in the attributes table. Some times my data can have only red and blue as values in the column and other times it may have green and yellow as well. I need to find I way to always make sure that the points with value red in the "Color" column will be displayed red on the map. All the other points need to behave the same way.

Any ideas on how to do that?

Hello @ABishop 

I am using ArcGIS Pro 2.8.1. But I think that I found what I was looking for. I don't think there is any way to do this simply by using Arc but there is a way to do it programmatically . Here are the solutions I found, all that is left is to add my own logic and it should work:
