The aim of this work is to analyze the influence of some of these environment factors on the design outcomes in terms of creativity, considering the potential emotion it can cause (relax or arouse). An experiment was developed to test the results generated in different settings combining environment factors that enhance creativity, in which designers were asked to develop different creative concepts. Different col-ours and music were combined in order to set arousing and relaxing environments. Results point to differences in the creativity parameters, according to the environment in which designers worked. Keywords: Creative process; emotion; concept generation 1. Introduction Creativity and innovation are two terms that totally condition business success. New products that are launched must meet a set of innovation standards and this responsibility is often determined by the creativity of the design engineer in charge of developing these products (Alves et al., 2007; Taura, 2016). For this reason, the designer’s creativity and the design process have frequently been the subject of study (Amabile, 1996; Csikszentmihalyi, 1998; Aizpun et al., 2015; Hu & Reid, 2018; Morin et al., 2018). From these numerous studies it has been observed that creativity does not only depend on internal factors within the
