Abstract
A computer-input stylus which provides visual color feedback when utilized in conjunction with a computer-implemented software-based drawing application. The input stylus includes a cylindrical body in a conical tip. A color display within the stylus is utilized to illuminate the conical tip with a color indicative of a currently selected color within the software-based drawing application, providing visual color feedback. The color display is implemented utilizing multiple light-emitting diodes or an active matrix liquid crystal display mounted within an optically transparent portion of the conical tip.
