Colors are a big part of psychology. Graphic artists understand this, as do advertisers. A color can set the mood, or kill the mood. Have you ever walked into a friend's living room to discover that the walls and ceiling were all painted blood-red? Or jet-black? Maybe, but probably not. Too much of a color can be enough to make someone feel a little nauseous, or induce a headache. The right color can help relax you.
My favorite color is green. Dark, forest green, to be precise. It reminds me of trees. Based on what I've read, green is the color of the heart chakra, and the energy that comes from it. Similarly, green in the aura can indicate natural ability in faith healing.
You can find the importance of colors throughout much of parapsychology, whether it's the color of a nonphysical plane, the color of a spirit guide's clothing, or a prominent color portrayed in a psychic vision. The soul is supposed to be able to see in perfect color.
So, what is color? Color is light. Color is something our brain uses to sort out different frequencies of light, as the photons hit our eyeballs. At some point in our species' evolution, natural selection favored this separation of frequencies, which helps us predict the weather, identify plants and animals, and see the blush in the cheeks of an attractive member of the preferred sex. Those of us that do see in color surely take it for granted.
There's actually a very wide range of light frequencies. We see purple at one edge of the rainbow, but there are other colors that are so purple we can't see them (whoa!). Ultraviolet light, x-rays and gamma rays are the purplest things we've got. The other edge of the rainbow is red, but infra-red is even redder than that. It's so red, we can't see it.
There's a mental separation between our rainbow colors and things like ultra-violet, or x-rays, but you have to realize that it's entirely in our heads. ROYGBIV is not special. It is not not not special. There is nothing particularly unique about the visible spectrum, other than it's the frequency range we can see.
Think of it this way. You go to a gravel pit, and there are chips and chunks of rocks all over the place, ranging from giant boulders to minute sand. Now imagine a guy sorting through these rocks with a basket slung over his shoulder, measuring each one, and only collecting rocks that were between one and two inches wide. Then he takes all of these stones aside, and arranges them into seven groups, by size. He calls the first group red, the second group orange...
Do you see where I'm going? And other animals have ended up sensitive to other frequencies of light. Birds, for instance, can see in ultra-violet. Because of this, they can get certain information through sight that we cannot. Presumably, information that's important for being a bird.
So, if you were to ask the question, is color a fundamental part of the universe, the answer is no. Color doesn't exist, any more than a distinction between one-inch stones exists in a quarry. Even though it's such a big part of our experience, it's just a method of organizing information.
So, with this in mind, I have to wonder why the seven chakras would somehow correspond to the narrow frequency band that humans can see. I have to wonder, in fact, why our very limited eyes have such a sway in the non-physical universe. Why do people who believe they have left their body been saddled with this limitation? Is this something we have to carry on into the afterlife?
And if your soul uses light to see after you're dead, you had better hope that its vision is 20/20, because I don't imagine there are any optical shops in heaven.
