How we see color

Red

Green

Blue

When we see color, we actually see light that is passed through or reflected from an object. What our eyes perceive as visible light are wavelengths. Our eyes are sensitive to three specific wavelengths. They are the colors red, green, and blue.

When you view your monitor, you see red, green, and blue light that is projected into your eyes. This is known as additive color. Additive color begins with black and adds red, green, and blue to produce the colors you can see. If you add equal amounts of red, green, and blue, you produce white. The images and colors you see on your screen are created using various amounts of red, green, and blue.

Primary colors

Notice the three primary additive colors red, green, and blue in the illustration. You can see that when all three colors are com- bined, you get white. However, look at the area where any two colors overlap. What you see is cyan, magenta, or yellow. Equal amounts of green and blue produce cyan. Equal amounts of blue and red produce magenta, and equal amounts of red and green produce yellow. The inks used to place color on your printed material are cyan, magenta, yellow, and black.

The colors in newspapers, magazines, and the documents you print are based on the light being reflected from the printed material and into your eyes. The color you see is subtractive color. Subtractive color begins with white light. Portions of the white light wavelength are then subtracted based on the colors present on the printed page. What this means is the light reach- ing your document is partially absorbed by the ink placed on the page. For example, when white light encounters cyan, it absorbs the red wavelength in the light and reflects blue and green toward your eyes.

If you add equal amounts of cyan, magenta, and yellow, you cre- ate black. When you combine these colors equally in your printed material you create what is known as processed black. Processed black when printed looks like a very dirty or muddy brown. Because of this, your printer has a black print cartridge to provide you with true black for all your printing needs.
