Table 1 adil Cal Examining the presence of the named principles of color effects in this group of buildings is presented in Table 1. The second group of buildings uses coloring at the level of the surface. Here, the design concept is in a two-dimensional sequence of composition that is applied in the envelope of the building. It cannot be necessarily connected with the size and shape of the volume(s) of the building and other parts of the composition — openings, etc. We found several ways of making composition, using one color with several tones of the same color (Fig. 3b and Fig.4a), or using two or more distinctive colors that are combined color combination (Fig. Ic). Single hue usage is not necessarily characterized by the monotone surface, but it is possible to use a combination of the several tones of the single hue, that from a distance act as a single color. The color choice is usually outstanding; highly contrasted to other parts of the building and the background. When using colors in this way, the highlighted volume is usually clearly defined and formed so it stands out not only by color but also by form. Color choice: Sometimes architects use corporate colors to strengthen the visual identity of the company (Fig 2a) that is now visualized through the building, but as well it is possible to use colors that are connected to the function (Fig. 2b — color of the wine in the winery), also color code can be used for nonverbal communication (way-finding) to make differences between separate parts of the buildings (Fig 1a and Ic).
