The first, primary, and most fundamental feature of human consciousness
/ the universe / God would be the binary distinction. Something versus
Nothing. Black / White, On / Off, One / Zero, Change / No Change, Yin /
Yang. In the picture there is only dots and lines on a white background,
symbolizing this quantum reality upon which all other reality is built
upon. The color red is the first color of the visible spectrum, red can
be thought of as the color of "one" or more correctly as the
energy process by which "one" transforms black to red.
The 'one' force is related or indentical to the strong nuclear force, the element fire, the masculine polarity, the Magician archetype (Tarot) and is particulate or digital in nature.
Anthropological note: In cultures whose language only recognizes a single color, Red is always the color to be differentiated from non color (i.e. some languages only name "dark", "light", and "red").
