When we give name to color, we usually describe our perception of light, as compared with our own experience and knowledge. Very often perception of color is a complex problem that needs to be described by mathematical, physiological, and physical theories. There is a clear description for the physical task of describing quantities for mixing color pigments. In this article, the author discussed original graphical decision for color equations: the color surface for natural mixtures. Light mixing theories describe the nature of color, originally in mathematical language of the physical principles for color mixing different substances. Color-mixing system were originally developed based on the three-component chromatic model, which tells us how color works in nature and how color mixing works with pigments. Color theory was developed to show how color pigment structures could be measured. In this article, an algebraic system is shown consisting of mathematical equations, given the surface of color mixing, gives measurement principles of color characteristics by the two quantities. This mathematical system has shown by graphical decision color mixing the nature of the physical 3-component vision. The original model of mixing equally well provides the numerical identification for color mixtures of two or three components pigments. Clear descriptions of colors on the color surface show the different characteristics of color, and the value that these colors have in light mixing as estimated by the vision perception system. Color surface is very important as a practical conception for understanding the quantitative description of color measurement technology. The color surface as a graphical model is mathematically necessary to describe the mixing color components of pigments, lights, and substrates. Each single color is positioned as a sum of several primary colors and can be applied in the separate physical task of measuring color, to reproduce color by technology. Color as the physical characteristic of a substance has the practical meaning in every day practice to guide through many types of color variations. Clear understanding and interpretation of color values is consist with the mathematical equations for color components, reproducing the white light absorption, reflection by the substances with regular color chemical structure, and describing substances such as solid, gases, liquids, organic, inorganic. In this article, an evaluation of the spread of chemical pigment components in growth process plants is demonstrated. We also studied seasonal fluctuations of organic pigment components with the example of ripeness for maturing fruits. We have discussed color structure spreading for toxic smoke, with visualization of the concentration of toxic substances in an open-air environment. Application of color surface for color digital measurement is practical in cases for color pigments spreading of chemical structures. This article has shown research result in organic fruit specimens, Sorby 'rowanberry,' a well-known medical plant, and specimens of toxic smoke. Color studies are necessary to get the quantitative description pigment structure in original specimens, technical identification color pigments. Color surface has important meaning for the physical perception of world.
