Sharp and smart geomorph.
Your coloured doors are clear and easy to keep track of. Of course in a computer environment where the players are exploring on the actual map they'd be a little bit of a give away .
Your coloured rooms give me an idea. I wonder if one could make deepening shades of red or something depending on the danger potential in the room. Course with my players, they'd kill themselves with an unguarded pointed stick .
I think you can find tutorials on the site that will help you cut out the scanning step to create similar maps. Might save you some time.
Thanks for posting.
Have some rep.
