Tilework Color Palette of Ghiyasiyeh School of Khargerd The Permanent Building of the Timurid Period in Khurasan

The fifteenth century, which coincides with the Timurid Empire in Transoxania, is a reminder of the brilliant past in the field of art, especially architecture. Meanwhile, architecture of schools is seen more than any other element of the art related to this era. Ghiyasiyeh school is one of the most beautiful examples of the architecture in the Timurid period in Khurasan. In this research, the diversity and color families of school tiling, as well as their organization, were studied and evaluated. Accordingly, a general categorization of the types of tiles in the school was first performed, then the colors used in each section and the color schemes were examined. Therefore, the main goal of this research is to achieve the palette of school colored families and to study the color schemes used in the existing tile types. Considering the wide variety of colors in the building, the question raised is how the Timurist architecture utilizes both the palette and color variation in tile production and the arrangement of these pieces together. In response, we gathered the results using field studies and non-refurbished tile colors as well as library studies, and finally, we analyzed the results by descriptive-analytical method. The results led to the presentation of the tile color palette of this collection and it was also found that the tile artist working on mosaic tiles used the colors of the cold family more in the background and larger dimensions and the colors of the warm family in smaller dimensions to emphasize his designs. It was also found that the Timurid artist, with awareness, designed and prioritized the color vision of the tiles. Gold has also been featured especially in cuerda seca tiles.
