Currently I have to enter color values manually to an ArcGIS Pro Style (.stylx), which is time consuming and laborious. I suggest the ability to add colors to an ArcGIS Pro style with a batch process or as a file. I envision something similar to the process of adding swatch files (.ase) to Adobe Illustrator. Alternatively the user could prepare a .csv with HEX, RGB, CMYK values, etc., color mode, and the other field values in Catalog that must currently be entered manually.
