Tough to recognize what's a door with dynamic light

Hi everybody!  I'm sorry if this question has already been asked.  But with all the comments about how to use doors with dynamic light kicking around, it was proving to be a real challenge finding the answer to a completely unrelated question. Dynamic lighting is great.  But my players have a hard time recognizing what's a door, and what's a wall, even when I use the thinnest line setting.  This isn't a problem in a cavern.  Just set the line behind the wall, and it's easy to see.  But in a keep with multiple rooms which the players could approach from either direction, it's difficult to recognize a thin patch of brown on gray. Drawing a shape on the map looks too jarring.  And welcome mats in front of every door is too goofy.  I'm wondering what other people do to clue players in as to where the doors are. 

Don't use the thinnest line.  Use a thicker line for doors, it makes them easier to grab and move.  Set it back a bit so that the players can see the door artwork on the map layer.

But what if the players come from the other direction?  That just makes the door harder to see...

Good point.  You can find a good looking piece of door artwork and drop it on the map layer, make sure it is bulky enough to stick out on both sides.

Oh geez.  Use a door to represent a door.  Sometimes the answer is too obvious.

There are neat transparent door icons in this post  that you can use in some situations. Though honestly, I just do what the above poster said and overcut the door line in a way where it's displayed best for the expected direction. If players surprise me, I just use the flip tool on door-lines quickly as possible.

Sometimes if the map walls are not built thick enough to make the presence of a door obvious, I will drop an  Invisible Token  with a small aura on it. Make sure the players can see the token's aura (on the token settings tab), but don't give them control, so they can't accidentally move it. Just set up one of these and copy and paste as needed.

Been using it this way for years. So far no complaints... easy to recognize...
