Compare and contrast pigment color with the color seen from a light. What is the difference between mixing pigment colors and mixing light colors?
Pigments are chemicals that selectively absorb and reflect different spectra of light. When a surface is painted with a pigment, light hitting the surface is reflected, minus some wavelengths. This subtraction of wavelengths produces the appearance of different colors. Most paints are a blend of several chemical pigments, intended to produce a reflection of a given color. Mixing pigments is subtractive. Mixing light is additive. Let's take the primary pigments, red, blue and yellow. Red pigment is red because the chemical it is made of absorbs (subtracts) blue and yellow light that falls on it and reflects only red light to your eye. Similarly, blue pigment is blue because it absorbs red and yellow light and reflects only blue. So when you mix the three primary pigments together, you produce something that absorbs all of the light falling on it in equal amounts and reflects nothing to your eye. Thus, it appears black. In contrast, when you mix only red and blue light, there isn't any yellow in it, so the resulting light appears purple (the complement of yellow). Likewise, if you mix red and yellow light it appears orange (the complement of blue). If you mix all three colors of light together (in equal amounts), the resulting light appears white because it contains all of the colors of the spectrum. This explanation is sound, although greatly simplified. The two summaries above are not my own, nor do I claim them as mine.
you notice pigments the colour you notice them, using fact they replicate a spectra of sunshine, with particular frequencies, and take up all others seen to the human eye. in case you combine distinctive monochromatic mild with distinctive colours (as seen on the television: purple, green and blue it quite is referred to as additive mixing, or magenta, yellow and cyanide that's the different technique) your retina will upload the colors up, and experience it as a distinctive shade. (by skill of including each and all of the three colours on an identical intensity, you are able to create white mild) while mixing pigments (they are chemical compounds) you get a clean cloth, which will replicate an different spectra of sunshine, which you will see as a shade
