Color in Dreams What do they mean? Or do they mean anything at all?

In the Heaven and Hell, Huxley talks about colors in dreams and how the colors doesn't describe the dreamer's personality. He said " Color in dreams and visions tells us no more about the personality of the beholder that does color in the external world". I think that if we dream in black and white , maybe the dream can be considered a natural dream, don't need any colors because in reality we perceive the colors of the objects or locations in our other side of the world, but the colors could be helpful so they can look real when we know they're not. I found a website, http://www.angelfire.com/realm2/amethystbt/colormeaningindreams.html that explains why colors in dreams are important and why shouldn't we pay any attention to them. For an example,red especially lighter shades of red can mean a sign of passion, energy, and life. The colors could also mean matters of the heart, blood, something that is important and should be understood, and danger. The color orange is considered to be a color of warmth, thoughtfulness, wisdom and sociability. In reality, when we feel depressed , stressed or happy in our lives , the colors in our dreams help left up our spirits or show us something dreadful that warns us about reality.
