What are Primary and Secondary Colors?
The primary colors are pure and main colors of the color wheel, being red, blue and yellow. They are colors that exist without the combination of others, while the secondary colors are formed by other colors , specifically from the combination of two primary colors, for example: green (red and blue).
Colors are visual perceptions through the cone cells that transmit the impressions that go directly to the nervous system. Studies affirm that the color formed is a product of the impression produced on the retina of the eyes by light after being emitted, diffused and reflected on objects, which is why it is indicated that the color corresponds to an internal sensation caused by the physical stimuli of nature.
In English, the phrase primary and secondary colors translates to primary and secondary colors.
Colors are classified into:
- Primary colors : they are pure colors, that is, red, blue and yellow.
- Secondary colors: they are the union of two primary colors, for example: green (blue and yellow), orange (yellow and red) and purple (red and blue).
- Tertiary colors: they are the union of a primary and a secondary color, such as: orange red, reddish violet, yellowish orange, greenish blue, yellowish green.
However, modern color theory disagrees with what was previously established, being a set of basic rules in mixing color perception, to achieve the desired effect through the combination of light colors or pigments. German poet and scientist Johann Wolfgang Von Goethe indicated that color depends on the perception of the individual, involved in the brain and the mechanism of the sense of sight.
- Primary light colors (RGB model):red, green and blue. The mixture of these three colors is called additive synthesis, which causes brighter secondary colors than the primary ones.
- Pigment Primary Colors (CMY Model):Cyan, Magenta and Yellow. The mixture of these colors is known as subtractive synthesis, resulting in the absence of light and the presence of black. For example: printing systems.
Warm and cold colors
The cold colors are blue, green and purple or purple, so they are associated with ice, water and moon that transmit sensations of cold, a name created by the German psychologist Wilhelm Wundt that determined the sensations of the human being before certain colors.
For its part, the warm colors correspond to those that transmit a sensation of heat, in view of its connection to the sun, fire and blood. These colors are yellow, orange, and red.
In the color wheel, the complementary colors are located at the opposite ends of the primary colors. As such, they are opposite colors that intensify and balance each other. In this way, the colors are complementary: blue – orange, red – green, yellow – purple.
According to psychology, the different colors have psychological effects, and various meanings are attributed to the different colors, such as: red is related to love and passion, yellow to envy and blue to fidelity.
In view of the effect it produces on individuals, colors are frequently used as a strategy in the world of advertising and marketing. They indicate that red stimulates the appetite, and that is why large fast food restaurant chains such as Pizza Hut, McDonald’s, Wendy’s, etc. use it in their logo and facilities with the aim of stimulating appetite.
