COLOR AND THE TRIGRAMS
The Masculine and Feminine Colors
The Later Heaven Arrangement of Trigrams
according to Connie Achilles
Electricity is the servant of the God-Mind. Electricity expresses the desire in the God-Mind for creative expression by seemingly dividing the One still light into transient waves of spectrum divided positive-negative colors of light. (TSOL p. 50)[1]
Traditionally, in Western culture,
three colors have been considered as primary—red, yellow and blue.
Today, in current color theory and practice, there are six primary
colors: red 
, yellow 
, green 
, cyan 
, blue 
and magenta 
Technically, these are the six primary chromatic colors. There are also the two achromatic colors of black and white —so altogether there are a total of 8 primary colors in the “color octave.”
Red , green , and blue are often called the "additive" primary colors, and refer to light. These are the positive masculine colors. Cyan, magenta, and yellow are often called the "subtractive" primary colors, and refer to inks or pigments. These are the negative feminine colors.
