Color is one of the most important factors of painting, but it is hard to get a nature color just like the real object. But this color picker can help you finish this hard work. The color picker pen enables colors in the environment to be scanned and instantly used for drawing. The sensor detects the color and matches it to the color display then the RGB cartridge located within the pen mixes the inks together to create the color that has been scanned. Korean designer Jinsu Park has created this color picker pen that basically brings the eyedropper to real life. Place the end of the pen against an object or surface to read the color, and the pen will automatically combine red, green, and blue ink to give you exactly the color you want.
