From Dreams Obscure
Often, dreamers don't pay attention to the colors in their dreams. However, focusing more attention on this aspect of dreams may help lead to a more accurate and fulfilling interpretation. For example: A dreamer dreams of a statue, which falls from its place on a mantle and crashes to the floor. Seems pretty broad, huh? However, if the dreamer recalled that the statue was green, then one possible interpretation could be that the dreamer's jealousy is leading to destructive ends. If a certain color continuously reappears in your dream, it may be time for you to figure out exactly what that color could represent. Your subconscious is most likely trying to comment on something by using that particular color as a symbol.
Below is a list of colors and their possible meanings. Please keep in mind that what one color represents to one person may be completely different for another; different cultures assign varying symbolism to particular colors. The list below represents a western culture bias.
Red: Lighter shades of red can be representative of excitement (especially sexually), passion, energy, and life. However, deeper or "weighed down" shades of red may be indicative of anger and vengeance. Notice how the stop sign is red; possibly a hint from your subconscious to cease and desist in a certain activity? Other possible meanings, depending on the dream's context, are: matters of the heart, blood, something that is important and should be understood, and danger.
Orange: Orange is considered to be a color of warmth, thoughtfulness, wisdom and sociability. Muddier shades of orange may be representative of pride or vanity, while golden orange denotes self-control.
Yellow: A bright yellow color represents "sunniness," joy, optimism, and intuition and mental stimulation. Muddier shades of yellow may mean blocked intuition, betrayal, treachery, and faithlessness. This color may be used by your subconscious to help ease you out of depression.
Green: This is the color of nature. It is also the color of development and growth. Lighter shades of green tending towards blue represent healing. Darker, muddier shades of greens represent envy and greed, as well as a stubborn and/or self-opinionated attitude. This color is also representative of money.
Blue: Blue is a cool, calming color, often used for relaxation and meditation. It is a very spiritual color, and is representative of truth, intellect, and justice. Muddy shades of blue may denote depression or moodiness. When this color appears in your dreams, it is probably a message from your subconscious telling you to relax and take things more slowly.
Violet: Darker shades of violet may denote a person who feels misunderstood or has obstacles to overcome. It too is a spiritual color, and brighter shades help inspire and stimulate, especially in relation to dream activity.
Black: Because this color is often regarded as the color of death, its appearance in our dreams may represent the death of old ideas or change. Another possible explanation is that it represents a hidden or rejected aspect of the dreamer. It is the color of mystery, the unconscious, and sometimes even protection.
White: White is often regarded as the color of purity and truth. Seeing this in your dreams may be a message from your subconscious telling you to regard the truth of a certain situation. It is also the color of completeness and innocence.
