This is a post I began quite some time ago thinking it would be a quick and easy one, since it concerns a topic I know very well.
But—perhaps due to my own inability to be brief—it turned out to be more involved than expected. Maybe I just have a hard time leaving out all the details. In any event, I set it aside until I had more time.
Then I had an idea for making this post a bit more fun (at least for me). The problem was: I needed to build a theatre! You see, this post is about color and light.
