Primary colors of pigment (like paint): Red yellow blue
Primary colors of light (like tvs): red blue green
Primary colors of ink (like printers): magenta cyan yellow black
Primary colors of your eyes: red green blue yellow (the yellow registers as a lack of blue)
So, it depends on what you're doing. White light (such as from the sun) has all colors in it, and if you filter it, you can remove certain parts. A cyan filter removes red, for example.
