A (Very) Brief Introduction to Color Theory

Today I did some research on primary, secondary, and tertiary colors for a poster I am working on. This is a very brief introduction to some of the basics of color theory. Primary colors can be mixed to create many other colors. The four primaries are red, yellow, green, and blue. If you are a human  being or a computer monitor your primary colors are red, blue, and green, which can be combined to produce over 16 million colors. If you are an artist or illustrator your primaries are red, blue, and yellow. RGB colors are additive, meaning they are mixed to create other colors. CMYK colors are subtractive, meaning amounts of color are subtracted from cyan, yellow, magenta, and black to create millions of other colors. Secondary colors are created by mixing the primary colors. The secondary colors are green, orange, and purple, if you are a painter or illustrator. Tertiary colors are formed by mixing a primary and a secondary color. If you are an artist your tertiary colors are yellow-orange, red-orange, red-purple, blue-purple, blue-green, and yellow-green. I will explore color theory in greater detail in future posts. A good reference for color theory is at this website:
