Wonder if folks with absolute pitch form emotional associations with different keys.

Collier gives his answer to that here: https://www.youtube.com/watch?v=hyXCWYqpId4&t=836s and it seems to be yes for him, without giving any details why(!)

I would say it makes sense - perfect pitch or not - every key has a different relationship to your own voice, which makes it feel different.
