In the past 3 weeks, I have painted 2 interior doors in my home in deep, vibrant shades. The door in my young son’s bedroom I painted in a cobalt blue. While our previously cream basement door got a lick of rich, red burgundy. Safe to say that I am a HUGE fan of the painted interior door trend. Painting an interior door in a bold shade is an easy way to add vibrant colour into your home, without having to commit to painting all the walls in a domineering hue.
