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.
