(48) The theory so long held of three primary and four secondary colors is purely exoteric, for since the earliest periods it has been known that there are seven, and not three, primary colors, the human eye being capable of estimating only three of them. Thus, although green can be made by combining blue and yellow, there is also a true or primary green which is not a compound. This can he proved by breaking up the spectrum with a prism. Helmholtz found that the so-called secondary colors of the spectrum could not be broken up into their supposed primary colors. Thus the orange of the spectrum, if passed through a second prism, does not break up into red and yellow but remains orange.

(41) In The Principles of Light and Color, Edwin D. Babbitt confirms the correspondence of the color and musical scales: "As C is at the bottom of the musical scale and made with the coarsest waves of air, so is red at the bottom of the chromatic scale and made with the coarsest waves of luminous ether. As the musical note B [the seventh note of the scale] requires 45 vibrations of air every time the note C at the lower end of the scale requires 24, or but little over half as many, so does extreme violet require about 300 trillions of vibrations of ether in a second, while extreme red requires only about 450 trillions, which also are but little more than half as many. When one musical octave is finished another one commences and progresses with just twice as many vibrations as were used in the first octave, and so the same notes are repeated on a finer scale. In the same way when the scale of colors visible to the ordinary eye is completed in the violet, another octave of finer invisible colors, with just twice as many vibrations, will commence and progress on precisely the same law."

(21) The Three Primary Colors are as follows: (1) Red; (2) Blue; and (3) Yellow. From these three primary colors all others are formed by combinations and blendings, or by the addition of Black or White. Thus, the Secondary Colors are formed as follows: (1) Green, derived from a combination of Yellow and Blue; (2) Orange, derived from a combination of Yellow and Red; (3) Purple, derived from a combination of Red and Blue. Further combinations produce other colors, for instance: Green and Purple form Olive; Orange and Purple form Russet; Green and Orange form Citrine.

(22) Black is really an absence of color, while White is really a harmonious blending of all colors. The blending of the Primary Colors in varied proportions produce what are known as the "hues" of color; and adding White we obtain "tints," while mixing Black produces "shades." Key to the Auric Colors An understanding of the basic character of the Three Primary Auric Colors, and of Auric Black and Auric White, gives the student the key to the whole range of auric coloring. For this purpose the following table is presented: The Red Group . Red represents the physical nature, and its presence always indicates the existence and activity of that part of the nature of man.

(52) In addition to the colors of the spectrum there are a vast number of vibratory color waves, some too low and others too high to be registered by the human optical apparatus. It is appalling to contemplate man's colossal ignorance concerning these vistas of abstract space. As in the past man explored unknown continents, so in the future, armed with curious implements fashioned for the purpose, he will explore these little known fastnesses of light, color, sound, and consciousness.

(37) In Meno, Plato, speaking through Socrates, describes color as "an effluence of form, commensurate with sight, and sensible." In Theætetus he discourses more at length on the subject thus: "Let us carry out the principle which has just been affirmed, that nothing is self-existent, and then we shall see that every color, white, black, and every other color, arises out of the eye meeting the appropriate motion, and that what we term the substance of each color is neither the active nor the passive element, but something which passes between them, and is peculiar to each percipient; are you certain that the several colors appear to every animal--say a dog--as they appear to you?"

(9) The following table of the Auric Colors will give you the key to the blending and shading in the luminous cloud composing the human aura.

(18) In addition to the ordinary colors named above, there are several shades which cannot be named, for they correspond to colors outside of the field of human vision, such as "infra red" and "ultra violet." Without going deeply into this phase of the subject, it may be said that the "ultra violet" auric colors denote high spiritual powers manifested in the direction of the highest and most worthy aims and ends; while the "infra red" auric colors denote psychic powers employed in unworthy ways and for base ends—as for instance, that which the occultists know as "black magic." There are two other auric colors which are impossible to describe in words, for there are no terms adequate for such expression. These colors are as follows: (1) the true primary yellow, which indicates the highest spiritual illumination of the intellect; and (2) true pure white, or a peculiar brilliancy and transparency, which indicates the presence of the awakened spirit.

(29) It is also a part of the teachings that the Three Primary Colors have a decided therapeutic effect, and that one may apply the principle in healing work. The colors may be applied either by means of physical colors placed in the environment of the person, or else held in the mind of the mental healer giving the treatment. Here is the Therapeutic Scale of Colors: Therapeutic Scale of Colors Blues, Violet, Lavender, etc. , have a cooling and soothing effect upon the nervous system, and upon the blood and bodily organs.

(28) It should be noted by the student, in passing, that the Green group of auric colors seems, at first glance, to be an exception to the general rule regarding the blending of the primary auric colors; and to manifest contradictions in character. For instance, it is difficult for the average student to comprehend why a blending of the spiritual blue and the intellectual yellow should yield a green indicating deceit, etc. A subtle analysis of deceit, however, gives the secret of this combination, particularly when it is noted that in certain of the less desirable of the green combinations there is combined a slight mixture of black and of red. It is not necessary to go into details concerning this particular point—it is enough to indicate the nature of the solution of the mystery. Again, there is a certain shade of Green, that which manifests in the prevailing colors of trees, plants, etc., which when shown in the auric coloring indicates a love of nature, etc. The following words from a celebrated occultist gives a valuable hint to those whose minds tend to keen analysis concerning these matters; this occultist says: "To those who are fond of analysis of this kind, I will drop the following hint, which may help them in the matter, viz.: The key is found in the fact that Green lies in the centre of the spectrum, and is a balance between the two extremes, and is also influenced by these two extremes in a startling manner." Important Suggestions The Rosicrucian teachers do not content themselves with instructing their students concerning the particular colors which, when seen in the aura, indicate the presence and activity of certain mental or emotional states in the person. They also instruct the student according to the celebrated principle of Action and Reaction, which forms an important feature of certain branches of the Rosicrucian teachings. That is to say they instruct the student that if he will hold in his mind the mental image of a certain color, there will result a reaction in the direction of the production in the student's mind or emotional nature of the feeling or emotion corresponding to that particular color. For instance, if the student will hold his thought and attention firmly concentrated on the Red group of colors, there will be awakened in him a strong passional emotion, and the manifestation of animal vitality and vigor, virility, courage, etc. Again, if he will hold in his mind in the same way the Blue group of colors, he will experience an uplift of spiritual or religious emotional feelings, and his nature will be quickened along those lines. Again, if he would stimulate his intellectual faculties, or reinvigorate a tired mind, he has but to concentrate on the Yellow group of colors to obtain the desired result. So, it is seen, not only do mental and emotional states manifest appropriate colors, but the colors themselves tend to produce their corresponding mental and emotional states. The action of Red upon the bull and other animals is explained in this way; also we have here a suggestion as to why a man "sees red" under moments of great excitement leading to physical action of punishment, etc.

(68) Timaeus: but when these colors are mixed and more completely burned, and black is blended therewith, the result is “violet.” “Chestnut” comes from the blending of yellow and grey; and “grey” from white and black; and “ochre” from white mixed with yellow. And when white is combined with “bright” and is steeped in deep black it turns into a “dark blue” color; and dark blue mixed with white becomes “light blue”; and chestnut with black becomes “green.” As to the rest, it is fairly clear from these examples

(67) Timaeus: Concerning colors, then, the following explanation will be the most probable and worthy of a judicious account. Of the particles which fly off from the rest and strike into the visual stream some are smaller, some larger, and some equal to the particles of the stream itself; those, then, that are equal are imperceptible, and we term them “transparent”; while the larger and smaller particles—of which the one kind contracts, the other dilates the visual stream—are akin to the particles of heat and cold which affect the flesh,
