The concept of bacterial paint having mind-altering abilities, turning passive entities hostile or further enraging hostile entities, is a quite an interesting concept. However, it is a bit strange that humans would have such a radically different reaction to the parasitic paint though. Especially since quite a few entities are also descendants of baseline reality life. Also some sections of the writing could be condensed/put in one place; for example, there's two mentions of parasitic paint's various colors on two opposite ends of the article. This isn't needed. Also the section that's like "if untreated, there won't be much of you left except…(insert a ton of body parts)" sounds like quite a bit of the person is left, lol. Could be shortened down to "there won't be much of you left but a pile of mush" or something along the same line. Last, there are mentions of almond water, post-decannonization of that material; it's likely that this article hasn't been updated past that time.
Overall, decent concept but definitely would need some readjusting to adapt to LA's current canon.
