This paper describes a method of using color to display the actual structure of a Pascal program on a color monitor. This enhancement not only increases a programmer's understanding of the code, but also aids in detecting common structural errors. The paper identifies several structures deserving of color and the properties that must be adhered to when assigning colors to these structures. A simple coloring scheme illustrates this discussion. The last section describes enhancements and directions for future research.
