In the same way as we find the elements of nature organized in their respective periodic table, so the colors are represented in an orderly manner according to their different shades by means of the chromatic circle.
One of the first models of the chromatic circle was proposed by none other than Isaac Newton in the 17th century. And it is thanks to this chromatic wheel that we can visualize all the different ranges of colors, allowing us to distinguish much better the gradient of each shade and the most harmonious combinations, contrasts, shades, mixtures and all kinds of relationships with each other in order to create color palettes for each design. Similarly, the circle shows how each of the shades are linked, categorizing them into opposites, complementary and adjacent. The chromatic circle is not, however, a perfect circle, since primary colors are usually more widely spaced than secondary and tertiary colors.
In short, it is a round format that serves as a sample to appreciate the so-called primary, secondary and tertiary colors. The main colors of the chromatic circle are: red, yellow, green, blue-green, blue and red violet.
Primary Colors: The chromatic circle is mainly cataloged into the three primary colors: yellow, blue and red, and as well as their different attributes: hue, intensity and degree. Light colors (additive) and pigment colors (subtractive) are also distinguished. They are known in this way because they are tones that cannot be acquired from the combination of others, as if we were talking about colors in the purest sense.
Secondary Colors: The secondary colors of the basic chromatic circle are green (product of mixing blue with yellow), orange (product of mixing yellow with red) and violet (product of mixing blue with red). These shades are obtained by combining equal parts of the primary colors.
Tertiary colors: They are those obtained after the mixture of primary and secondary colors, mainly classified in six: yellow-green, yellow-orange, red-orange, red-violet, blue-violet, blue-green.
