Mixing of pigments such as dyes & paints to obtain different colours is not the same as mixing of coloured lights.

doug has it. the pigments absorb all color but the one you wish to see, which is refracted. If you are talking about a printer, the pigments (toner) mix and different particles refract different types of light and that light mixes to produce the desired effect.
The primary colors in pigments are red, blue and yellow (with variations in hue - the mixing of those colors - and saturation - how much color there is, and how much black you mix in. This is the essence of 4-color process. there are 4 colors (cyan, yellow, magenta, and black) and mixing them together in different ratios produces different refractions. In computer graphics, this is CYMK mode, which is used for printed materials and PMS colors.
The primary colors in light are red, green and blue (RGB mode for graphics. This is obvioulsy for on-screen work like website design.) The main difference is that you don't have to add black to the mix. Tou would just turn down the intensity of the light and the resulting absence of light would be black.
I hope this helps.

pigments of colouring stuffs whereas colouring light as u say is energy and there is a lot of difference between energy and just a pigment. as u would have studied under spectrum that when blue, red and green lights mix they form white light but it is not the case with pigments. got that!!!

The physical proporties of light come from the wavelengths of individual colors. Colored pigments in paints are made in a variety of ways more often based on chemical properties. Hence the primary colors of light are different for those in painting.

when dyes r mixed, it is a kind of a physical one. so u get a kind of resultant of the colors.
whereas in the case of mixing of colored lights, the way of contact depends. they scatter for sure and the way they do it, results in diffrent results.

It's the difference between radiated and reflected light.

If you are interested in the resulting color they are very close except some minor deviations.
