Subtractive Color
Photographs and objects of nature create color by subtracting or absorbing certain wavelengths of color while reflecting other wavelengths back to the viewer. This is called subtractive color. Example - The common apple, it is seen as "red" by the human eye or a digital camera. The apple really has no color (light energy of its own), it merely reflects certain wavelengths of white light that cause us to see red and absorbs most other wavelengths. Color paintings, color photography and all color printing processes use the subtractive process to reproduce color. In these cases, the reflective substrate is canvas (paintings) or paper (photographs, prints), which is usually white. | ||||

Subtractive Color
A colorspace in which colored pigments are added to white paper. We start with White (paper) which is the presence of all colors and use Cyan, Magenta, Yellow pigments to subtract from the image to achieve black. The pigments subtract colors from the white light reflected off the paper. Yellow ink looks yellow because it absorbs (subtracts) everything except the yellow from the white light that is illuminating the page leaving on the reflected yellow light. (See: CMY and CMYK)

Subtractive color
A subtractive color model explains the mixing of paints, dyes, inks, and natural colorants to create a range of colors, where each such color is caused by the mixture absorbing some wavelengths of light and reflecting others. The color that an opaque object appears to have is based on what parts of the electromagnetic spectrum are reflected by it, or by what parts of the spectrum are not absorbed.
