The study is the second part of a previous study which explored the effects of color pairs on warmth perception in interiors. The main aim of this study is to investigate the effects of material pairs and their single materials on warmth perception in interiors with the same methodology, since paired materials have not been investigated yet. Each material pair and their two single materials were assessed by 32 different participants, thus 96 different participants assessed three groups of material models (Fabric and Timber material pair, Fabric and Plasterboard material pair, Timber and Plasterboard material pair, and their single materials) under controlled conditions. Results indicated that as single materials Timber and Fabric have the same level of warmth and are warmer than Plasterboard whereas there is no difference between their pairs. Findings revealed that these two natural materials are perceived to be warmer than the artificial one and pairing them on interior walls provides similar level of warmth. © 2018 Society for Imaging Science and Technology.
