Brewster theory is a theory that simplifies color to 4 color groups. The fourth group is the color of the primary colors, secondary, tertiary, and neutral colors. This theory was first declared in 1831.
Groups of color in this theory are often arranged in a circle of color brewster. Brewster color circle can explain the theory of complementary colors, split complementary, triad and tetrad.
That is the basic colors that can not be obtained from a mixture of other colors. Colors belonging to the primary colors are red, blue, and yellow.
Is the result of mixing primary colors. For example, the orange color is the result of a mixture of red with yellow, green is a mixture of blue and yellow, and purple is a mixture of red and blue.
Colors are derived from a mixture of primary colors with secondary colors. For example, a yellowish orange color is a mixture of yellow with orange.
If the three primary colors are mixed, you will get a neutral color. This color is usually used as a balancing contrasting colors in nature. Usually the right mix will lead to black.

Circle of colors ranging from primary to tertiary colors can be grouped into two major categories, namely the class of hot colors and cool colors. Hot color of greenish yellow to red. Whereas cold colors beginning from reddish purple to green. Hot colors can create an impression of a hot and close. Cool colors on the contrary will result in cool shades.
