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 of the plurality of light producing devices positioned at an angle with respect to a vertical axis that passes through center of the imitation candle device and configured to project light from a distance onto the flame element to illuminate a particular area on the flame element, the plurality of light producing devices positioned to project a set of overlapping light beams, wherein the overlapping light beams form an overlapped area in a center 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 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 the light beams 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 of the exterior wall provided by the one or more colored lighting devices based on the signal indicative of the color of the surface.
