tary CMYK support can be found [PLUGIN-SEPARATE].)

This is the mode used in printing. These are the colors in the ink cartridges in your printer. It is

the mode used in painting and in all the objects around us, where light is reflected, not emmitted.

Objects absorb part of the light waves and we see only the reflected part. Note that the cones in

our eyes see this reflected light in RGB mode. An object appears Red because Green and Blue have

been absorbed. Since the combination of Green and Blue is Cyan, Cyan is absorbed when you

add Red. Conversely, if you add Cyan, its complementary color, Red, is absorbed. This system is

subtractive. If you add Yellow, you decrease Blue, and if you add Magenta, you decrease Green.

It would be logical to think that by mixing Cyan, Magenta and Yellow, you would subtract Red,

Green and Blue, and the eye would see no light at all, that is, Black. But the question is more

complex. In fact, you would see a dark brown. That is why this mode also has a Black value, and

why your printer has a Black cartridge. It is less expensive that way. The printer doesn’t have to

mix the other three colors to create an imperfect Black, it just has to add Black.

I did not follow the 'add Red' bit. White light is incident on paper and the ink-pigments absorb certain colors and reflect certain other colors - therefore our eyes only receive certain wavelengths - this is subtractive. In a computer monitor, RGB is generated by phosphor excitation and mixed and goes straight into our eye.

Green + Blue = Cyan #got it.
Cyan falls on paper+pigment and is absorbed #got it
left over wavelengths are now travelling to my eye..
so how is Red 'added'???? He does 'adding' of colors and I don't get that.. Could someone explain it clearly.
