A device such as a computer stylus may have a color sensor. The color sensor may have a plurality of photodetectors each of which measures light for a different respective color channel. The color sensor may also have one or more light-emitting devices. Control circuitry may use the light-emitting devices to illuminate an external object while using the photodetectors to measure reflected light to determine the color of the external object. The electronic device may have a housing with an elongated shaft. The shaft may have a tip and an opposing end. The tip may be configured to emit electromagnetic signals that are detected by a touch sensor in a touch sensitive display. The color sensor may be located at the end opposite the tip, may be located at the tip, or may be optically coupled to the tip using a light guide.

A touch screen having a capacitive touch-sensitive pad overlaying a display area incorporates one or more slide features each having conductive plates. The conductive plates are located outside the display area of the touch screen and are powered via one or more connections to existing touch sensor circuitry comprising the touch-sensitive pad. The slide features of the touch screen do not obstruct a user's view of the display screen and, when compared to conventional touch screen slide features, reduce the circuitry required for detecting and/or processing a slide touch.
