In figures #11 to #13 you’ll see the colors that belong to two systems at the same time.

Figure #11

This figure demonstrates which colors of the nature are reproducible by both the RGB (additive) and the pigments (subtractive) system (area colored yellow). This is the largest area common to two systems at the same time.

Neverteless, you can see that the RGB system of a PC monitor or a TV screen is unable to reproduce all the colors of an oil painting — and reversely.

Figure #12

This figure demonstrates which colors of the nature are reproducible by both the RGB (additive) and the CMYB (subtractive) system (area colored violet).

The practical consequence is that it’s impossible to print correctly the colors you see on your screen.

Figure #13

This figure demonstrates which colors of the nature are reproducible by both subtractive systems: the pigments one and the CMYB one (area colored dark green).

The practical consequence is that it’s impossible to reproduce correctly all the colors of an oil painting with the ordinary color printing techniques.
