This is a very common feature that will help us understand the principle of consistency. It consists of the ability of a data mining tool to understand the syntax of a piece of code, consequently assigning common colors to tokens pertaining to the same logical role into the code.

This would, therefore, diminish the net value assigned to the tool:
