Incorporate the 4-color tool into ArcGIS

[MaraKaminowitz]

Often there is a need to differentiate polygons by color independent of value or category, i.e. when creating a map of Census tracts or zip codes for a region. The current options are:

1. Have ArcMap color 1,000+ polygons individually
2. Use something like the 4-color script to create a new feature with a color field and symbolize from that.

#1 takes forever and can crash ArcMap. #2 is also time consuming and not always possible if you are need to work with an original file that can't/shouldn't be altered.

It would be great if there was some sort of native 4-color symbology option in ArcMap.

That is great to hear!!   Can't wait to use it when it is in Pro @KoryKramer   

It will be invaluable to many of us!

That's 13 and a half years since it was requested.  ArcGIS 10.0 was 9 months old.  It's weird how seemingly simple implementation ideas fall off the development cycle but orbit back around eventually.  It's a nice to have, it's not core functionality I suppose is why.

Has anyone tried this yet?   https://pro.arcgis.com/en/pro-app/latest/tool-reference/cartography/calculate-color-theorem-field.ht...

I missed this functionality.   Looks pretty good and quick too
