you guys know that trick where you place the door sideways (relative to the door frame) in the seemingly "open" position?
that way, doors start off in their "closed" state and when they're visually "closed" they're actually open
this technique actually confuses zombie-like mobs and makes the door immune to them breaking it
that's what i use lol, ig it could be a green colored one?
that said, doors that are placed this way open more often than not into the "blue" one rather than red
