ABSTRACT:
A computer-input stylus which provides color control 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. Color selection is accomplished utilizing a color selection input actuator mounted to the cylindrical body of the input stylus. The color selection input actuator, such as a trackpoint device, is utilized to drive a pointer around within a color palette, such as the so-called RGB color triangle.
