Color Symbolism:
Use caution when teaching about color symbolism. Symbolism of colors vary
from culture to culture. Be aware that many Pagan sites will come up if you have students search this topic. (See note to students)
Color is considered one of the most useful and powerful design tools you have. People respond to different colors in different ways, and these responses take place on a subconscious, emotional level. In our American culture, black has long been associated with death, while white is believed to signify life and purity. In the Orient, however, white is the traditional color of mourning. In the United States, black has also come to suggest sophistication and formality. Americans generally associate trust an stability with the color blue, while Koreans have this reaction to pink and other pastel colors.
In the Western Culture:
Purple and gold are often associated with Royalty, wealth and opulence
Red, White and Blue reminiscent of the American flag, immediately convey notions of patriotism and, to some extent, conservatism.
Green has taken on a very strong connotation as the color representing ecology and concern for the environment, however, it also conveys meanings associated with money and the suggestion "to go ahead" which is obviously derived from traffic lights.
Colors represent holidays and seasons of the year.
The Fall foliage colors of Red, orange, yellow, and brown are clearly expressive of Thanksgiving. Halloween: Orange and Black. Red and Green represent Christmas. Purple and Yellow and other pastels colors represent Easter.
Blue, Red, White and Grey = Stability, Power, Trustworthiness, Conservatism
Yellow, Brown, Orange, Green = Nature, earthiness, warmth
Red, Orange, yellow = more warmth
Blues and Aquas = water and coolness
Primary colors (Red, Blue, Yellow) = Convey fun
Color symbolism in Zulu beading.
Young girls learned bead work and the meaning of the symbols and colors used from their older sisters. The bead work was usually worn as a head or neck band. Men depended on female relatives to explain the code. The patterns and colors can also tell what region a woman comes from and what her social standing is.
Native American Color Symbolism
Colors in Native American culture often symbolize different things from
culture to culture....African cultures have different meanings....and
so on. Colors symbolize different qualities in various European cultures.
Native American color symbols--Cherokee
The Four Directions
Colors were associated with the four directions.
Blue represented North which meant cold, defeat and trouble.
White was South representing warmth, peace and happiness.
Red was East, the color of the Sacred Fire, blood, and success.
West was black the color meaning problems and death.
Other colors also had special meanings.
Brown was good but yellow meant trouble and strife.
The circle was also a basic symbol for the Cherokees.
The council houses were circular and the fire inside was
built so that the fire would burn in a circular path.
The stomp dance and other ceremonies were performed
in a circular pattern.
Navajo Meanings of Colors
This information was posted to Getty Teacher Art Exchange by Christine Merriam
TheFour Sacred Mountains and directions are associated with colors. The Navajos belief is that their Creator placed them on the land between the following 4 mountains representing the 4 cardinal directions:
White: Mount Blanca (Tsisnaasjini‘ - Dawn or White Shell Mountain) Sacred Mountain of the East near Alamosa in San Luis Valley, Colorado
Blue: Mount Taylor (Tsoodzil - Blue Bead or Turquoise Mountain) Sacred Mountain of the South north of Laguna, New Mexico
Yellow:  San Francisco Peaks (Doko‘oosliid - Abalone Shell Mountain) Sacred Mountain of the West near Flagstaff, Arizona
Black:  Mount Hesperus Dibé Nitsaa (Big Mountain Sheep) - Obsidian Mountain Sacred Mountain of the North La Plata Mountains, Colorado.http://www.lapahie.com/Sacred_Mts.cfm
The principal colors, white, blue, yellow and black are linked to the four sacred mountains as well as the directions- Red is often considered a sacred color and represents sunlight. (source for this is off line now)
White Mountain Apaches
Four sacred colors of the White Mountain Apaches in east central Arizona contrast
interestingly with the Cherokee colors:
White represents the north, source of snow
Yellow is east, where the sun comes up
Green is south
Black is west, home of the sun‘s setting
These colors are used in a variety of settings, from the tribal government
seal to the ribbons on the cane of Changing Woman (the girls‘ puberty
ceremony).

The Flag of the Flag of the Iowa Nation
The color of the streamers brings together the four primary
colors in Native American art, the black, yellow, red and white. These
colors are said to represent the four races of man and the four prime
directions of the compass. With its use of color and its chosen emblems the
flag of the Iowas may be the most typical of all Native American
flags.

On Teaching the Color Wheel:
FromMarvin Bartel: For any age that does not already "know" the color wheel - try a more scientific approach.
What if we did NOT show anybody the color wheel? What if we started with only primaries and black and white without saying that they are primaries and neutrals? What if you ask students to see what they "discover" by experimentation when we direct them concerning which colors to combine and which colors and neutrals to combine? This is not exactly "playing around" but it is "directed research".
I suppose it is the scientific method being used in art.
What if we ask them to "invent" a chart or something that helps them remember the combinations and their results?
If anyone tries this - or has tried this approach - let me know and I will forward your results to Professor Bartel.

TO STUDENTS: This page is not "authoritative" - I am not an expert on this topic. This page was created first for my students to give them an awareness of symbolism of colors in different cultures. Some of the listings come from Pagan sites which would not be acceptable for my students to view from school - so I copied the lists (without permission). If you are doing research - look for sources that have been researched and can be verified. My students came up with their own meaning for colors they used.   ~Judy Decker
