A great way to address lighting in a hallway with a low ceiling is to create repetition using a flush-mounted ceiling light. This repetitive pattern can create interest and drama when you don't have the space for a larger fixture.
Sherwin Williams Dignity Blue. I am in love with this color. Slightly brighter than navy. Just a touch off-beat without going full-on "hipster coffee house". (I first painted the ceiling Blue Chip, and it was totally hipster coffee house level offbeat. Not what I was going for.)
