The idea of color temperature is widely used in numerous significance branches in science and technology most of all in the lighting and imaging and broadly environmental design areas. This review paper aims at discussing the phenomenon of color temperature in details with respect to its definition, assessment, and impact on human and technological aspects. Colour temperature of light that is another, Basic characteristic of the light sources is the colour temperature which describes spectral density of power of the source in terms of Kelvin (K). In this paper, the author explores the basics of black-body radiation and correlations between black-body radiation and colour temperature and how different light-handing devices including; incandescent bulbs, LEDs and natural sunlight emit light with varying colour temperatures. The specific application of homography is discussed in various fields such as energy efficient lighting, use in photography and cinematography, healthcare, and agriculture. Furthermore, the effects of color temperature on the human circadian cycle and well-being are briefly described. Through a review of current research findings, this paper discusses possible ways of altering the color temperature so as to meet specific practical appliions for better energy efficiency, user experience and environmental conservation. Finally, in light of the present review the final discussion turns to future extensions and trends for colour temperature modulation, with particular attention to the contribution of further advanced technologies for developing newer and smarter lighting systems.
