The paper describes the technology of manufacturing small architectural forms of gypsum. The required appearance (color) is achieved by coloring the product in bulk (adding color to the water, which is mixed with gypsum). The appearance of the products with different percentages of color in water is given. The method of expert evaluation revealed consumer preferences. Studies were conducted for three colors (red, blue, violet). The preferred tonality when dyed in bulk is the tonality obtained by adding 50% tint, and less preferred when adding 10%. The results of the study in three batches of samples showed that this consistent pattern does not depend on color. There is a consumer need for a wide range of tonalities within a single color scheme.
