In the trigrams the 'different' line decides the gender. One or three yang is male or yang, one or three yin is female or yin.
In the Shogua is a description of the origin of the trigrams [Baynes: 274].
There are six primary
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. It is the difference between shining (yang) and absorbing or receiving (yin). See the article of Connie Achilles
And the old page I made about the colors
Red is the color of the Hephaestus stone, Vulcan's stone.
The frequency of the lines in both hexagrams and trigrams is low at the bottom line and high at the top line. Low frequencies have the power to reach far. The two trigrams with a 'different' line at the bottom have this power. The rumble of an earthquake travels for miles through the earth and according to the Chinese in antiquity thunder and lightning come from the earth as well. Wind can reach even further in the space below heaven.
The sons belong with the earth (two yin lines, 1 yang line), the daughters with heaven (two yang lines, one yin line).
Yellow is the color of the Greek god Hermes, the messenger.
Whenever we mix the three additive colours of light we reach white light (the picture is of clouds in sunlight. White is difficult to show on white)
Whenever we mix three color pigments together we reach black, the color of yin (the picture is 'fertile earth', pitchblack is a harsh color).
