Sometimes it can be difficult for designers to fully understand a color due to the fact that most resources are printed on paper and two-dimensional. For the Mexican designer Moisés Hernández the color of a three-dimensional object can be influenced by different features and elements. When light interacts with shape and texture, the perception of the object can change completely, creating different feelings and emotions.

ST Circle, designed as a new design tool, would allow designers, architects and creatives not only to understand color in a three-dimensional and real way, but also to enhance creativity.

The 90 stones of the wheel are divided into 30 different colors and three types of surface, to show how the color changes depending on the incidence of light on each surface. Depending on the roughness on which the light is reflected, it will create reflections or shadows. The system is, therefore, divided into three levels: the first is represented by flat surfaces where shadows and light are more evident on the curvatures, the second is an intermediate point, having a continuous surface with small defects and the last, instead, exemplifies the color in a rough surface where the light passes through the different holes of the stone.
