Venger's Decks - Dungeon Crossway

Dungeon Crossway - Deep in a network of underground tunnels sits a crossway, an intersection of corridors. The ground is crumbling and chocked with blood stains, the corridors lead towards two doors, one painted green and the other purple. Torches on the walls light the way, and although neither path from the cross section gives away any clue as to which corridor and door should be chosen, one must be walked nonetheless. Which will it be?
