“I hate (let’s say, the color blue) because my toxic ex likes it and therefore because they’re a bad person, everyone who likes blue is a bad person and should die!”

Limited and generalizing.
In your example, I think this is a defense mechanism more than anything. People deal with grief of separation in different ways. This looks dumb on the surface but it’s like burning your hand on the stove. You only need to do it once to be fearful of and therefore extra careful with all stoves. Person who likes blue and broke their heart = stove.
