The problem of setting a realistic three-dimensional subject color surface on the border of two environments with a minimum number of settings for visualization software is studied. The aim of this work is the technique of three-dimensional color modeling of objects to build their images. Theoretical bases of formation of color and perception are considered. Fresnel formulas for calculating the reflection and refraction of light when monochromatic light wave is passing are analyzed. The classic way of illumination with three points for realistic three-dimensional object images modeling is considered. General guidelines for configuring color highlights and specular reflections of smooth surfaces based on the description of physical properties of metals and glass are provided. Individual cases of specular reflections of gold and copper are considered. The results of using techniques for rendering complex scenes with gold and glass items are shown.

Keywords: three-dimensional modeling, reflection, roughness, color, light, glass, metal, gold, realistic image.
