In our Masonic journey we figuratively start in a "condition of darkness" and in answer to our desire for light we are given Blue Light, as Blue is the principal color of the three degrees of Ancient Craft Masonry.
If we proceed to the Chapter of Royal Arch Masons, colloquially known as "Red Lodge", we are met with the next level of light.
Combining these two lights together, the Council of Cryptic Masons gives us Purple, and a binary pattern is confirmed.
White could be understood as the Celestial Lodge Above, where the Great White Throne may be found. But my question for the contemplative Mason is: Where are the Green, Teal, and Yellow Lodges?
