We have introduced a few unique styluses that allow you to write or draw on tablet, but if you want to more accurately use color, the Chromopen stylus design concept will be a nice solution.
The unique concept stylus is designed by designer Ehsan Sayyad. Chromopen stylus comes with a built-in camera, so you can use it to catch colors directly from the scene you’re painting, while the integrated AMOLED display can show you the captured colors, you can also change some settings via the display, a scroll wheel and two buttons such as color mode, brightness, contrast, exposures and etc. Most importantly, when Chromopen stylus closes your tablet, the color data will be received by the tablet with the new penabled technology, and the brush’s color will also be changed. After the break, check out the image demo. Unfortunately, Chromopen is still a design concept at present.
