Accessing the uses of color in carpet enables us to open a window into the designers’ viewpoints and the way they treated colors in carpets. In analyzing carpets, apart from the practical aspects, color and the way it is used is underlined in the aesthetics of carpet. The purpose of this research is to offer a way to measure the color proportion by considering the effect of light colors on audience’s perception of color in the carpet. The research was conducted by experimental method and by taking into account the properties of color scattering in carpet, resulted from the scattering of scheme and presence of a dominant color in the background, which also relies on Agden Nicholas Rod and Frans Gerritsen`s color theory. This paper by introducing hypothesis of height of colors in carpets, through three case studies of carpets from the Safavid era, and by using Image J color analysis software, during two tests of Pure Color Measurement and color value assessment, develops color analysis. The paper seeks to answer the question as to whether or not the use of color in the carpets complies with any rules. It indicates that the colors in carpets are used as interlocking layers which only through analysis become recognizable and increase the illusion of convexity. Hence the results show that one of the most important phenomena in taking on carpet colors is the phenomenon known as virtual color height which can be achieved by forming the contrast of saturation in the margins to create a kind of virtual depth obtained by increasing color distances and eliminating simultaneous contrast. Using this method can help the carpet designers with picking the right colors and add to the richness of Persian carpet colors.
