In the Lord of Rings what colour is door?

This is a bit of a tricky question! The Lord of the Rings doesn't explicitly describe the color of the doors in the Shire, where the hobbits live. We can assume they were simple and practical, perhaps wood in earthy tones like brown or green.

However, if you're thinking about a specific door, you need to be more specific! Do you mean:

* The door to Bag End? We only see this door from the outside, and it's described as being "round and green".

* The door to the Mines of Moria? The entrance to Moria is a massive black iron door with a massive, carved wooden door behind it.

* The Black Gate of Mordor? This is a colossal iron gate, described as "black as night."

So, depending on the door you're thinking about, the color can vary quite a bit!
