Recent work concerning preferred LED lighting for interior materials was presented at the AIC conference in Tokyo. Therewith an earlier publication „Influence of lighting conditions on the appearance of typical interior materials“ is followed up. Preferred visual appearance iswas accessed for a set of 12 colors taken from the Natural Color System (NCS) catalog and a set of 8 types of wood surfaces. The results of the study demonstrates that certain hues fit better to lighting with higher correlated color temperature (cooler light) and other hues fit better to lighting with lower CCT (warmer light). The observed reactions to wood surfaces lead to the assumption that mainly hue determines the correlated light temperature of the LED light source that is preferred.

Scientific publication „Influence of lighting conditions on the appearance of typical interior materials“ by Dr. Ruta Lasauskaite Schüpbach, Markus Reisinger und Björn Schrader is published in Color Research & Application. The article reports two experiments that investigated how lighting influences perception of various materials. The first experiment shows that cool color temperature of the light source is preferred for materials of blue color (cold hue). Warm color temperature of the light source is preferred for materials of warm hue materials and those materials that have natural reference (e.g., grass). The second study shows that materials tend to appear softer under LED light source compared to other light sources in our setup. Finally, future directions in this research area are discussed.

To demonstrate and study the spatial interaction of light and color the department of interior architecture at Lucerne University of Applied Sciences and Arts runs a dedicated workshop room. Equipped with various types of light sources and a rich collection of painted samples the workspace is suitable for design work as well as for perception studies.

To study qualities of the spatial experience is the core activity in the center of competence for interior architecture. With innovative partners these insights are translated to prototype spaces and future solutions.
