I had a hard time taking photos of the whole wall, because the wall is has a sliding door with sheer curtains. I repainted the beige on the left-hand wall, and replaced a dark green paint with the blue. I also replaced dark green curtains with the polka-dots from Ikea.
This is the top of the curtains.
And this is how the color looks against the chocolate brown of the mantle above the fireplace. The room is so much brighter, I love it!
