Okay, so I'm surprised no one mentioned this.
I got stuck in pink world because the note says "The Father was messing with one of the chandeliers".
The item you have to interact with is a candelabra, not a chandelier. Chandeliers are the hanging light fixtures on ceilings. I thought it might be the candelabras, but after trying each one and it not working, I spent ten minutes looking for a chandelier before looking up a youtube video and realizing I must have just misclicked.
Also, in Yellow World, if you jump over the cart in the corn maze, you get softlocked.
