We had our hallway painted the same day as the door. It was a pale minty green that I'd been unhappy with for years. We chose Sherwin-Williams Canvas Tan. I won't even try to post a photo because our hallway is impossible to photograph. It's long and narrow and not well lit. The digital swatches online of Canvas Tan seem much darker than what I see on our walls. I'm super pleased with the results. Canvas Tan has lightened up the hallway and contrasts nicely with our Bleeker Beige (Ben Moore) trim color. We left the ceiling the darker shade of green that contrasted so well with the previously lighter green walls. The painters (both women, by the way, and fantastic!) kept commenting on how cool the light walls look with the darker ceiling. The walls are also an eggshell finish which has a beautiful sheen and reflects the light so nicely both during the day and at night. What a difference a couple of coats of paint can make!
UPDATE, 10/20: Here is a photo I snapped the other day of the hallway. It turned out better than I had expected. It gives some idea of what the Canvas Tan paint color looks like. The trim is Bleeker Beige. The ceiling is actually green, but I don't recall the name of the color, as it was painted many years ago.
