Is there a blog post or something on how to properly use color tags?

{"ops":[{"insert":"Curious in particular about how archidekt propagates color tags between decks. I've seen some carry over and some not. Was curious as to what I am doing to make that happen. \n\nAlso, \"Set All\" is not super clear about what it does. I assume it just adds that tag to every card in the deck but i am not sure what the purpose would be to do that besides resetting all to default.\n"}]}
