Strange behavior and different color of text in IDE

I have a sketch that is acting strange, I noticed that the color of the text in the IDE is tan on some portions of the program and black in others of the a similar programming structure. It is like the IDE recognizes one but not the other.

Any thoughts?


Each library declares its keywords in a keywords.txt file and that is used
to colour symbols that match. For instance if you mis-spell a library function
you'll realise since it stays black.

The same is true for built in types and keywords like int and for. Its called syntax
highlighting. In particular commented-out sections don't get coloured, which I
am guessing is what you are seeing.
