} CMYK is a subtractive printing model:
}
} Magenta (Red + Blue) - Cyan (Blue + Green) -> Blue
} Magenta (Red + Blue) - Yellow (Red + Green) -> Red
} Cyan (Blue + Green) - Yellow (Red + Green) -> Green
Easier to remember like that:
1 : single magenta (the reddish tank, alone)
2 : single cyan (the blueish tank, alone)
3 : 1+2: magenta and blue : mix of two: a kind of dark blue/violet
4 : single yellow (the yellow tank)
5 : 4+1 : magenta and yellow : mix of two: a kind of red/orange
6 : 4+2 : cyan and yellow : mix of two: a kind of green
The number is a binary encoding of the tank/ribbon to use.
