Sometimes I walk into a client’s home during the day, and it’s dark; either surrounded by trees or perhaps north facing (and they start talking about pale colours–which will not help). And not a single light is on. That’s when I feel like I need to give people permission to turn a light on, certainly in the darkest corners anyways.
Years ago, I lived in one of those box apartments, with windows only at the front of the living room and bedroom (with an overhanging balcony) . At the back was the dining room, right next to the walk-through kitchen where I had a floor lamp. The first thing I would do when I walked in, was turn this light on because it gave the illusion of having a window in that corner. It was on all day, anytime I was home.
So please, especially in the winter, do yourself a favour and keep a light on in the darkest corner of your house! Trust me, it will make you happy!
