Colors

The psyche often makes use of color symbolism to convey information in dreams. It is often asserted that people rarely dream in color. This is untrue. When the dreamer particularly emphasizes having dreamed in color, this simply means that he remembers the colors. As far as interpretation is concerned, this means that the dream is giving additional significance to the information conveyed by the use of these colors.
The following should be considered when interpreting the
individual colors: 
Black must be regarded as a signal of a state of non-awareness in the sense of a standstill. 
White can also be a reference to a state of non-awareness, like that which exists before the start or after the end of the psyche's conscious life. White can thus indicate forebodings of death.
Yellow is like gold. In a dream, it is the color of mental, intuitive activity.
Red is the color which most excites our attention. Red is the symbol for the dynamics of life. It is also a symbol for animal instincts and aggression. Orange is a particularly strong signal for activity.
Blue is the color which symbolizes the intellect. It indicates clear-headed deliberations and dispassionate thinking.
Purple is a signal for especial significance. 
As new life begins in spring, when fields and meadows turn a fresh green sheen, this color has an extremely positive meaning. 
Color test series over a period of years showed that brown is preferred by neurotics and indicates unconscious complexes.
Violet in a dream symbolizes conflict situations arising from the opposition of body and intellect.
