A brief explanation by Pastor Brian regarding the color coding of his notes:
Some times colors are used just to arrest my eyes attention to a different point in my document. Colors(or bold, italic, or underlines) break up the text so when I glance down on my notes I can find things, or the next point, very quickly. This helps me keep my eyes up on the listeners rather then burying my head in my notes.
Here is a simple guide & somewhat of a method to my color madness.
