Dual Attributes of Color

Color is the light visual effect by the human eye, brain, life experience generated. Our eyes have seen the light, by a very narrow wavelength range of electromagnetic waves generated by the electromagnetic performance of different wavelength different colors. In this paper, the author based complex spectrum color theory, from a number of color characteristics, summarized the dual color attributes, namely: light is an electromagnetic wave energy and vector nature. People in color signal processing are divided into two phases, the first stage is feeling stage, and the second stage is perception. Compared with the wavelength domain, in the frequency domain the color is evenly distributed. The color of the physical attributes and mental attributes are interdependent and complementary, it will only combined together to form a unified color science.
