Designing for Hope: Biophilic Color Associations and Their Relevance to Clinical Settings

To consider one common aspect of biophilic design (BD; i.e., color) and its relationship to an important element of well-being (i.e., hope).BD is multifaceted making the identification of critical design elements difficult. Further complexity is introduced given that practice assumptions stemming from the biophilia hypothesis may be questioned. Consistent with the biophilia hypothesis, the author considers the study's findings from the perspectives of evolutionary psychology and psychobiology.One hundred and fifty four adult participants engaged in one of the three experiments. Using colored test cards, Experiment #1 sought to determine which of four biophilic colors (i.e., red, yellow, green, or blue) evoked the strongest experience of hope. Considering this color alone, Experiment #2 sought to manipulate "color depth." Participants were asked to identify what color depth evoked the strongest experience of hope. Experiment #3 sought to determine if the outcomes of Experiments #1 and #2 were due to a priming effect. All participants were asked about color associations they held.Experiments #1 and #2 demonstrated that yellow at maximal color depth evoked the strongest experience of hope (p < .001). Experiment #3 demonstrated that no priming effect was evident (p < .05). No participant had a strong personal preference for/against yellow. Natural world color associations existed for yellow, green, and blue. Red held emotive associations.These findings clearly associate yellow with hope. From the perspectives of evolutionary psychology and psychobiology this suggests color cues can evoke time-dependent motive states. Implications for practitioners designing spaces of hope within healthcare facilities are considered.
