Before there was any color in the universe, before the creation of life, or knowledge, or time*, there were only two beings in the whole of existence, and these beings were Black and White. Together, they were the great Everything and the great Nothing, and although they were opposite in all ways, the two stood side by side always as equals.
These two were the only beings in existence, and one of them was purely Good, and the other purely Evil. However, they were not certain which was which, and they quarreled over the matter without end. Without knowledge, there was no answer to their argument, and so both were left maddened by their dilemma.
Once the two had said all there was to be said without resolving their quarrel, Black decided on a new way to find the answer to their question. Black said, "Come here, White, and stand facing me," and White did as Black commanded.
When the two stood facing one another, Black said to White, "Take your hand and reach into my body, and when you feel hot and cold shapes against your fingers, seize them. You must pull them out without looking at them."
White did as Black commanded, reaching into Black and pulling out the hot and cold shapes without looking at them. These three shapes were the first primaries: Red, Yellow, and Blue.
Then Black and White saw them and said together, "You are our children, and so we command you: tell us which of us is Good and which is Evil!"
But the three primaries did not understand the difference between Good and Evil. Leaving their parents, the three came together in a triangle and whispered a plan to create all the understanding they would need, and more besides. For such understanding to exist, they decided to create the place called Earth, along with its creatures, and the Three Peoples—fay, humans, and spirits—whose actions would be determined to be Good or Evil, so that others could look on and judge their behavior. The primaries then divided their work evenly:
Red, the child of body and life, was born of blood. Therefore this primary created the soil from which grew plants, and the living creatures of the world, filling them with blood, flesh, and bones.
Yellow, the child of mind and revelation, was born of knowledge. Therefore this primary created truth and awareness, so that all the living beings on the Earth knew what they needed to accomplish in order to survive.
Blue, the child of soul* and destiny*, was born of luck. Therefore this primary created time and meaning*, so that all predestined events could occur as they had been ordained by fate*.
But even all this was not enough to truly prove the nature of Good and Evil. To help finish their work, the three primaries joined one another at the edge of a great lake, and together they became a rainbow in the sky. The rainbow came down to Earth again and split into many different colors, and these fell upon the Earth to finish the work of creation.
Thus it is known to all of the Three Peoples that rainbows bore reality—for, at the onset of life and knowledge and time, only the colors existed, and together they mixed and painted and created until the world itself was left in their wake.
When they finished their work, the Three Primaries were satisfied, and they resolved to be reborn again and again unto the Earth so that the world would never be incomplete without them. And because a great argument was the impetus that led to the creation of the universe, the Three Peoples shall continue to harbor war and disagreement among themselves and each other until the end of time—for in their hearts, they recall that without strife, there can be no new beginnings.
*Folklorist's Note: Modern etymologists are divided on the specific attributes of the third primary figure, BLUE. Ancient human and fay languages of all types have offered a variety of meanings for each characteristic surrounding the third primary, with the most common English equivalents being "time" and "destiny," but also including other words such as "fate," "spirit," "meaning," "luck," and countless others.
