The three primary colors of yellow, blue and red have distinct characteristics relating to the Trinity. Blue and Red are opposites, from the standpoint of direction. Blue is recessive, Red is aggressive. Blue is the smallest light-wave of the three and red is the largest. Yellow stands in the middle, between the two, almost like a balancing point between them. It is the middle length light-wave.
The colors can be metaphoric of human personalities. (See Man's Soul (personalities)) Red is the fiery, emotional Sanguine, Blue is the analytical Melancholy. Yellow is the clear decision-making Choleric. The mixture or blend of all three colors depicts the Phlegmatic.
Blue correlates to the Son or Word, Yellow correlates to the Father and Red correlates to the Holy Spirit. With the human soul, following the same pattern, the mind correlates to the Son and the color Blue. It is analytical, Melancholy and detailed, with the smallest wavelength. (People who are Melancholy in their personality temperament learn by visual systems, primarily).
As stated above, the human will correlates to the Father, and the color yellow. It is the middle wavelength, between blue and red. The vibrancy of yellow is symbolic of the Choleric's aggressive, active will to ‘get things done’. (People who are Choleric tend to learn by auditory systems successfully.)
The emotions of the human soul correlate to the Holy Spirit and the color Red. It is impassioned and incites response. It is the longest of the three primary color waves. It is the most noticeable color of the three and it draws attention to itself. From the standpoint of human personality it relates to the Sanguine, the ‘life of the party’, the one with ‘charisma’. (People who are of this temperament tend to learn more effectively kinesthetically, being involved in physical activity. They also become disinterested if they are contained in un-involvement.)
The blending of all three colors, especially in their pallor, can portray the unassuming personality of a Phlegmatic.
Interestingly, as the color Yellow is between Blue and Red, the Will stands between the Mind and the Emotions. One can oftentimes observe a Choleric personality function in both the realm of the Mind and also the Emotions, as the Choleric touches both.
As in body types (see Man’s Body) we find that there are mixtures of different possibilities in a variety of combinations, which produce an array of different personalities. Ultimately, there are as many variations as there are shades of color.
