Color Theory

To explain the color theory and be able to understand how colors are related and what manner we perceive them. The process used is the one utilized to make dyes and pigments it is Newton Subtractive model. This model it is based in the chromatic circle developed by Isaac Newton when he observed the effects of light going through a prism. The formation of color.  According to subtractive model, colors start to form with three primary colors red, blue, and yellow.  Mixing these colors you obtain secondary colors orange, violet and green. The tertiary colors are obtained when we blend a primary color with a secondary color of equal parts.  All other colors are considered variations of these twelve basic colors either by combinations between these colors or by blending with white and black.

Primary colors are those pure colors that cannot be obtain by mixing with no other color from which obtain, together with white and black and any other color.  The primary colors are red, blue, and yellow.

Secondary colors are those that are obtained when mixed with primary colors between them. The red and the blue form violet; red and yellow form orange; blue and yellow form green.

Tertiary colors are those that are obtained when we mix in equal part’s primary colors with secondary colors.

Pure colors are the ones that are integrated in the chromatic circle without blends with white, black and grey.

Hue it is that which makes green green and blue blue or violet violet. There are many different hues that we can see but there only four basics hues: yellow, red, blue, and green. We know that yellow and red are neighbors of sort because they are connected through reddish yellow, orange and yellowish red. Similarly for blue and green, red and blue, and blue and yellow. The two pair of colors that are not connected in this way are yellow and blue on the one hand red and green on the other. We can think of these as diagonally opposed. We think of white and black as colors but as colors that do not have a hue; They are called achromatic colors. What it is yellow? We can not really express it. We can only say the most yellow yellow is that in which we see neither reddishness nor greenish. The other 3 fundamental hues can be defined in comparable way. In the middle between yellow and red we have orange; between red and blue we have violet; between blue and green we have turquoise; between green and yellow we have chartreuse. Between the four basic hues and the four intermediate hues we have many more hues in each of the sections

Value or Strength indicates the grade of brightness of a color related with black or with white. The type of value or strength goes from a saturated color to a dull color. While the saturated color it is the intensity, brightness or purity of the color, the dull color it is described as spotted or blurred.

Neutral colors are those who cover from white to black going through the grey color. Includes all the colors predominantly the grey color, raw white color and shades of maroon color, from the creamy colors to the tan color.
