Please consider including a tool to symbolize polygon according to the four colortheorem. It would be very useful to represent layers with polygons where is distinctly different limits.
I have used a VBA sample years ago in ArcMap 9.?. I sure could use something like it again.
See: Four Color Map
I'm probably not getting it, but can't you do this already using unique symbology and color ramps? You just need to create a four-color color ramp, or am I mistaken.
In mathematics, the four color theorem, or the four color map theorem, states that, given any separation of a plane into contiguous regions, producing a figure called a map, no more than four colors are required to color the regions of the map so that no two adjacent regions have the same color. I hope this helps as an explanation.
Makes a lot more sense now. Thanks
Here is a Five (5) Color Map solution which has worked for me: https://www.arcgis.com/home/item.html?id=5fa04ce288284c999f70464e1c3b2e82 just in case someone else needs something now.
