RGB, because of my church.... (Score 0)

The reason being, whenever I make it to church, they have those stringy-ribbon bookmarks in the hymnal (the book with the music in it) Guess which colors they have? Red, Green, and Blue.

So, at the beginning of the service, I flip through and put the red ribbon at the page for the first hymn, the green for the second, and blue for the third. RGB! I now know in which order to flip to the bookmarks.
