Typically people paint the paneling and leave the trim stained but I actually like the stained paneling better than the trim, and its lighter so I wonder how it would look to paint the doors?

HI -- There is too much wood going in all directions so something has to go and just paint is not going to work . I would re-move the wood from the walls and just have drywall .This will then feature the beautiful floors which is more valuable . A nice wall color and then the doors might not need to be painted then . Track lighting the length of the hall ceiling . You could then have a different color or a painting on the end wall to give an interest /destination focal point .

get some light paint in there! add some tables, flowers, art... anything with color
