This was my plan:
I have this absurd hallway of doors ~
Some bright yellow paint to liven things up because yellow has this wonderful reflective property and is perfect for a dark, dingy hallway. I'm a huge fan of brightly painted hallways, it's such a nice surprise, and who doesn't want to be led somewhere by a fun color? Then to complete the transformation, Duck tape! I love the playfulness of this and the best part is of course that when I change my mind it's an easy removal!
All this fun for a quart of paint and $4 worth of tape - who knew?
