The aura is made up of a person’s electromagnetic field and can be read in more detail by experienced people. Reading auras is not an exact science, but it has been shown to be remarkably accurate in some cases. The color most common with negative attitude or anger is red.
This answer does not include mention of colors because Aura reading is subjective and also because Americans seem to have such limited ability to see the world around them objectively when it comes to matters of their own emotions and mental state; it’s hard enough for readers without bringing into account someone who has no idea what they are looking at! Try re-reading this sentence if you liked this one better: “Reading auras accurately as well as the colors that are seen is subjective and also due to the fact that Americans don’t know how to read anything other than what’s presented to them.”
May I ask what part of the world you live in? The five colors mentioned, red green blue yellow orange, are actually primary colors! Those ARE the primary colors. You cannot compare primary colors with secondary colors because the latter are derived from the former to create even more colors. You cannot derive red, green or blue without either white or black in some form. The five colors mentioned are actually primary colors and NOT secondary colors which change back into their respective primaries when mixed together in equal parts.
Color therapy is an ancient Chinese art that I have studied. I think it is wonderful that you want to learn more about color. However, in my studies, red was never taught as a negative color! Red has many different properties depending on where the spectrum falls in the visible light area of its range. The primary colors are what they are and cannot be changed unless you go back in time before pigments were created and the world was in black and white.
I am sorry if I sound argumentative, but considering that red is a primary color, not a secondary color like orange that must derive from one of the primaries to be made; this question seems rather simple. It is also important to add here that while people’s individual opinions matter, their personal opinions aside, red is a primary color and cannot be derived from any other color in the spectrum.
