The
Advanced Advertisements plugin by minimoney1 already uses More Colors (for TF2) and Colors for anything else, and is a superset of this plugin. Also, since you are basing your work on Tsunami's plugin, I would have recommend you posting in that thread instead of making your own without even giving a link to the original.
Judging from the title, you have also not changed the version number, so you're messing up the stats too.
