Understanding the deep and meaningful meaning of colors I think changes everyone’s life for the better. I’ve studied the topic so often that it feels elementary. This reference gives more of the typical meaning of colors generally and in application to dreams:
The colors in our dreams can also be related to work needing to be done with the chakras. Inge Ås has a book on this topic of colors and the meaning of chakras written in Norwegian.
Colors have added to the beauty, comfort and expansion in my life. In Arica, the School of Scientific Mysticism we wore a different color every day that coincided with the planetary assignments of the days:
Monday, white or silver for the Moon
Tuesday, red for Mars
Wednesday, blue for Mercury
Thursday, yellow for Jupiter
Friday, green for Venus
Saturday, black for Saturn
Sunday, orange for the Sun
Since I wear neutral colored pants almost entirely, my tops are hung in rainbow order in my closet. If I dream of a color in a positive manner, I will wear that color. Otherwise, I choose the color that “feels” right for my day.
