South Korean designer Jinsun Park has envisioned a pen that reverses the process, taking a tool developed for the computer and porting it to physical reality.
Park has designed a concept pen that adapts Photoshop’s eyedropper tool for real life. On one end of the pen is a camera that captures a complex, real world color. Then, like an inkjet printer, a computer in the pen calculates the mixture of red, green and blue ink needed to replicate the color photographed by the camera. Ink in the perfect proportions then flows out of the ball point on the other end of the pen.
