There is an ancient mystical tradition that each character in the Hebrew alphabet also has a meaningful numerical equivalent. This tradition is called Gematria. It stands to reason that if a letter can be translated into a number, then that number can be given a chromatic value as well. By mapping each character’s position in the Hebrew alphabet to correspond with a color on the visible spectrum, we can translate these chromatic values from the text. We can translate the text into light.
