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 individually2. 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.
EXCELLENT IDEA! I'm surprised this idea doesn't have more votes. It's a no-brainer. EVERYONE, wants it without any doubt at all. Perhaps most people aren't familiar with the 4 Color Problem as the name for the problem they face every day. They just don't know the name for it and that the solution is readily available.Please, ESRI, implement an option in the automatic symbology generator for polygons that will ensure that any two adjacent polygons will not have the exact same color. The problem has been solved for years and everyone who draws maps with polygons faces this issue. The classic solution is 4-color, but preferably it would let the choose a number 4 or larger to increase variety in the map.Just create a button and use the script referenced above!C'mon, ESRI, you can do it! Version 10.1. :)Also, the script referenced in Chris' post breaks down in version 10. Can this be updated please, if it's not going to be directly implemented in ArcGIS.
I second this idea. Hope it could be implemented in ArcGIS Pro as well.
