Something I Did Not Know About Paint

The clerk at the paint counter at HD recommended we use dark primer (tinted grey) for the areas we are going to paint with dark, bold colors - like Finn's room.

Jennifer consulted with Finn and learned that he wanted red and green in his room. Afraid of that looking like Christmas, she persuaded him to use other colors, too. These thumbnails show what we are thinking of for how the colors will layout. Well, they are how I am thinking of it. I haven't reviewed this with anyone yet.
