The multi-colour illuminated sign displays an indicia or house address number in changing sequence of colours. The back lighting is provided by three groups of plurality of light emitting diodes. One group of the light emitting diodes is operative to generate a primary blue light, a second group of light emitting diodes is operative to generate a primary green light, and a third group of light emitting diodes is operative to generate a primary red light. Varying combinations of these primary lights produces a plurality of colour back lighting which are reflected and refracted by various reflective and refractive patterns to enhance the visibility and aesthetic appearance of the indicia.
