I was in Settings in Studio changing the colors in my scripts, and I came across "Preprocessor color", which I have never seen before.
I looked up "Preprocessor" on the Wiki and there were no results.
What is a preprocessor?
There is no ROBLOX Wiki page dedicated to PreProcessor. However, check out the Wikipedia definition.
"In computer science, a preprocessor is a program that processes its input data to produce output that is used as input to another program. The output is said to be a preprocessed form of the input data, which is often used by some subsequent programs like compilers."
