I want to color all my feeders in my electric network in arcmap based on feeder ID Field in every Feature Class in the network , so i want to have every feature with same Feeder ID to have same color , i found a tool but is not working and causing arcmap to crash , the tool name is network color tool .
I am not sure which tool you are referring to but you can symbolize by an attribute such as feeder ID with symoboling by category - unique values. You would have to set the same colors for all the feature classes or you could combine them all into one feature class and then symbolize depending on the data. Here is a link to the symbology settings. Drawing a layer using categories—Help | ArcGIS Desktop
