Knew yellow pretty confidently, once I googled wtf “hangdog” is.

Did briefly consider green because of duck and swallow, but rejected the idea. Never heard of grouse, and hawk didn’t occur to me at the time as a verb.

Blue never occured to me at all. Never heard of the Munster or Partridge families.

K-pop and K-Mart occured to me. Never heard of the others.

Other things I considered: pop art, street art. Cheeses including Swiss, Munster, and a few others that showed up as pretty obscured when I googled for them, but seemed just believable enough for me to go with the idea. There were other ideas, but honestly I forget. I was so lost with it.
