I have finished my painting project!
I ended up painting the two main walls light green and the fireplace olive green. I'm really happy with the way it turned out. I love having colour on the walls but the green we chose is subtle enough to be considered neutral (which I don't care about right now but I might when we decide to sell. When we were condo-shopping, Shawn and I saw one place that had a navy blue bedroom and a dark maroon bedroom and another that had a mustard yellow / bright green colour scheme. We left both places immediately.)
I've got a lot of the olive green paint left so I'm tempted to paint the bathroom but laziness is winning out at this point. Maybe I'll do it in a few months. Maybe not. Who knows?
