How do i customize the Text Editor or color tag parts of my code?

Question

How do i customize, extend the Text Editor or color tag parts of my code?

1. I would like visual studio to color code parts of my code can i use #region and give it a color?

2. Is there any way to make the background between two parathesis have a different color? ( i want each code "block" to have it's own color?

I've looked here for some insight but they all are implemented based "on what you select". All i want is to have the Text Editor "render" the text in a different way based on some rules.
