>"I mention plants and such not entirely because they dream. But because they're sentient and are made up of color, which is the very essence of sentience and makes up everything in the Marioverse: including things that do dream. Blackness should dream, and so should all the other colors since in terms of art and coloring, black is the presence of all colors. Color Splash utilizes it in terms of coloring, not light or optics, so black is, again, the presence of all colors. Since black is sentient and (spoilers) the Paint Stars in Color Splash are sentient, each color should be sentient as well."

The Black Paint was made sentient because all the colors were mixed; assuming they're sentient because of this special case is an association fallacy. Saying that the colors would have the same properties of black paint is a Burden of Proof when it clearly shows that it’s entirely different by itself in nature; regular colour would not have this. (Also, scans for the Paint Stars being sentient?) Now... Adresing your sunshine argument...

>"Petey Piranha in Sunshine is also made entirely of goop and is able to sleep, so that also proves that paint alone can dream. That was my purpose: proving that every atom is sentient and that pretty much everything in the Marioverse is thus sentient because of that."

The paint and colors in the game is a result of the paintbrush used by Bowser Jr; as you already know, however, the paint enemies in the game are sentient via being able to walk and various Mario enemies being there — Those enemies are the manifestation of the brush, something actually gave them life in the first place. And lastly... Dreaming isn't the same as sleeping to begin with.
