I enjoy the swirling love arrows in question 5! The pictures also look like overhead views of funky aircraft, especially anger. Ok, only anger, really. I'm surprised that blue didn't take the top (leftmost here) spot for sadness in question 4, but I suppose grey is glum as well. I also think it's interesting that green does not feature prominently, seeing how it's everywhere in nature! Maybe other emotions, like tranquility, would help to yield a more complete spectrum. I'm also a bit surprised by the absolute dearth of purple, I associate it with joy quite powerfully! This reminds me of that game where you give someone a word or phrase and get them to tell you the image it conjures in their head right away. My favourite result of that is the fact that 'you're welcome' produces a close up of Trident Gum in my head! Probably associated with a polite exchange of gum in the days of my earliest youth.
I can't say what sort of parody it is, but it's pretty well done, whatever it is.
