Color printing yields yellow, red and blue yields magenta (a purple hue), and green and blue yield cyan (a turquoise hue). Only yellow is counter-intuitive. Yellow, cyan and magenta are merely the "basic" secondary colors: unequal mixtures of the primaries give rise to perception of many other colors all of which may be considered "tertiary." While there are many techniques for reproducing images in color, specific graphic processes and industrial equipment are used for mass reproduction of color images on paper. In this sense, "color printing" involves reproduction techniques suited for printing presses capable of thousands or millions of impressions for publishing
Color wheel uses two colors that look appealing together. More advanced color schemes involve several colors in combination, usually based around a single color—for example, text with such colors as red, yellow, orange and light blue arranged together on a black background in a magazine article. Color schemes can also contain different shades of a single color; for example, a color scheme that mixes different shades of green, ranging from very light (almost white) to very dark. Analogous colors are colors next to each other on the wheel. For example, yellow and green. Monochromic colors are different shades of the same color.
