Colour Picker Pen

Korean designer Jinsu Park has created this color picker pen that basically brings the eyedropper to real life. The pen can scan objects and detect the colors, then users can then use the detected color to draw.

The color picker pen has a RGB Color Sensor for detecting color, a color display showing the color detected. When color is detected, the RGB ink cartridge inside the pen will mix the inks to create the color.
