The use of symbol and color code in ArcMap derived from paper map. Symbol and color is a must for a paper map. Today we mostly use interactive web map, such as google maps, apple maps. You don't have to use symbol and color in web map. Most of web map I developed here are "color blind" , no symbol. no legend. 'Color Blind' system is simpler and easier to read. Color Blind system(click here) has NO symbol, NO color difference, NO legend. "Classified" map(click here) is color blind sample.
ESRI's color code system use different color to represent the different category. There are 2 ways to categorize. Most use is 'categorized by unique value'. Secondary most use is 'categorized by value range'. You can find all of that in ArcMap symbology dialogue window.
My color blind system fully implement 'categorized by unique value' in a simpler and non-confusing way. However, Partially implement 'categorized by value range' only on calendar date format. I have not be able to think of a 'magic' way of doing it. ESRI's 'categorized by value range' is complex( distribution deviation ) and confusing by color code. In my color blind system, I try to create a better (simpler, no confusing) way to categorized by value range, but I am not satisfy with any of the idea I found so far. I am still experimenting new idea.
