A hair ornament includes multiple light-emitting diodes (LEDs) which are manufactured as a single component so that their combined output can be focused on the end of a bundle of optic fibers. The fibers may be woven in the hair or wig of a wearer of the ornament. For a preferred embodiment of the invention, three LEDs, each of which emits a primary color (generally red, green or blue), are provided. Each LED is coupled to a flasher circuit having both variable frequency and variable duty cycle. At low frequencies (i.e., less than about 18-20 flashes per second), the flashes are seen as discrete colors. However, as the frequencies are increased, only a single color is visible. The color of that single color can be varied over the visible spectrum by varying the duty cycles of the three LEDs. One use of the preferred embodiment is to adjust the projected color to coordinate with clothing of the user.
