        To easily distinghuish quotes by person, each person gets a personalized color with his quote. The way this is done, is by taking the name of the person as a randomizer seed, and generating a number between 0 and 18. This is because Materialize offers 19 colors suitable for the background.

        When this number has been picked, then the color name associated with that number is sent to the template for rendering."""
