<P> There are two types of color mixing: Additive and Subtractive . In both cases, there are three primary colors, three secondary colors (colors made from 2 of the three primary colors in equal amounts), and one tertiary color made from all three primary colors . This point is a common source of confusion, as there are different sets of primary colors depending on whether you are working with additive or subtractive mixing . </P> <P> The additive mixing of colors is unintuitive as it does not correspond to the mixing of physical substances (such as paint) which would correspond to subtractive mixing . For instance, one can additively mix yellow and blue by shining yellow light together with blue light, which will result in not green but a white light . As in this example, one should always have the mixture of light in mind when considering additive color mixing as it is the only situation where it occurs . Despite being unintuitive, it is conceptually simpler than subtractive mixing . Two beams of light that are superimposed correspond to additive mixing . </P> <P> By convention, the three primary colors in additive mixing are red, green, and blue . In the absence of color, when no colors are showing, the result is black . If all three primary colors are showing, the result is white . When red and green combine, the result is yellow . When red and blue combine, the result is magenta . When blue and green combine, the result is cyan . </P> <P> Additive mixing is used in television and computer monitors to produce a wide range of colors using only three primary colors . A pixel is a juxtaposition of these three primary colors . Projection televisions typically have three projectors, one for each primary color . </P>

What two colors can you mix together to make yellow
