1. An imitation candle device, comprising:

  • a flame element shaped to resemble a candle flame and protruding from top of the imitation candle device;

    a plurality of light producing devices located within the imitation candle device, each light producing device positioned at an inclined angle with respect to a vertical axis of the imitation candle device and configured to project light from a distance onto the flame element including an area of overlapped light beams in a central area of the flame element;

    a color sensor located inside the imitation candle device to receive reflected light from a surface that the imitation candle device is placed on and to detect a color of the surface;

    one or more colored lighting devices positioned to illuminate an exterior wall of the imitation candle device; and

    an electronic circuitry coupled to the color sensor, to the plurality of light producing devices and to the one or more colored lighting devices, the electronic circuitry to control projection of light produced by the plurality of light producing devices onto the flame element to simulate an appearance of a candle flame, the electronic circuitry further configured to receive a signal indicative of the color of the surface from the color sensor and to adjust illumination provided to the exterior wall based on the signal indicative of the color of the surface.
