This is not a ordinary pen, it is a weird pen. In fact, this is a pen that can replicate any color and become the ink of the pen. Just place the end of the pen against any object or surface to let the pen “read” the color, and the pen will automatically combine red, green, and blue ink within the pen and come out with exactly the color you want.
This pen win the Red Dot Design Award: design concept 2008 in education section, by designer Park Jinsun. It is currently just a concept.
