Cognitive performance and emotion are indifferent to ambient color

Abstract

Folklore has it that ambient color has the power to relax or arouse the observer and enhance performance when executing cognitive tasks. We picked a number of commercially available colors that allegedly have the power to alter cognitive performance and the emotional state, and exposed subjects to them while solving a battery of cognitive tasks. The colors were "Cool Down Pink", which is said to produce relaxing effects and reduce effort, "Energy Red", allegedly enhancing performance via increased arousal, "Relaxing Blue", which is said to enhance attention and concentration, as well as white as a control. In a between-subjects design, a total of 170 high school students carried out five tasks (number series completion, mental rotation, and memory for word categories, word pairs, and geometrical figures) while exposed to one of the four colors. The emotional state of the subjects was measured before the beginning and at the end of the experiment. The ambient colors did not have the predicted effects, neither on cognitive performance nor on the emotional state of the participants.

Individual Differences in Hemodynamic Responses Measured on the Head Due to a Long-Term Stimulation Involving Colored Light Exposure and a Cognitive Task: A SPA-fNIRS Study

“…Our finding (that there is a positive correlation between the number of excellent performers and relative leftward PFC activity) is in accordance with previous research [ 42 ] which concluded that during the VFT, subjects with excellent task performance showed a left-dominated dorsolateral frontal asymmetry, while moderate performers showed a right-dominated frontopolar asymmetry [ 42 ]. Moreover, slightly better VFT performance with red as compared to blue light exposure is in line with many color and colored light studies which have proposed that red improves task performance in comparison with other colors [ 73 , 74 , 75 , 76 , 77 ]. In particular, red enhances the performance for “overlearned motor”, “proofreading”, “target shooting”, and “basic strength” tasks [ 76 , 78 , 79 , 80 ].…”

Which Attribute of Ceiling Color Influences Perceived Room Height?

“…Apart from that, the good news for the designer is that the choice of hue and saturation can be made (almost) entirely on aesthetic grounds, because their effect on the perceived height of an interior space is absent or small. Following these considerations, hue and saturation can be applied in order to obtain a further design goal, such as an intended emotional effect of the paint (e.g., Acking & Küller, 1972;Franz, 2006;Odabasioglu & Olguntürk, 2015;Wilms & Oberfeld, 2017;Yildirim, Hidayetoglu, & Capanoglu, 2011; but see von Castell, Stelzmann, Oberfeld, Welsch, & Hecht, 2018). Note that this does not rule out potential interactions of surface color with other factors that likely do influence the perceived layout of interior spaces, such as furniture and decor.…”

Effects of Interior Color Schemes on Emotion, Task Performance, and Heart Rate in Immersive Virtual Environments

“…To display interior color with precision, a majority of relevant studies manipulated color variables of interest while keeping other confounding factors constant in physical spaces (e.g., laboratory and real‐life spaces). For example, a significant portion of studies represented interior colors using simple methods (e.g., a colored wall, printed colored image, or colored light) in a laboratory space (Al‐Ayash et al, 2016; Küller et al, 2009; Kwallek, Soon, Woodson, & Alexander, 2005; Öztürk, Yilmazer, & Ural, 2012; von Castell, Stelzmann, Oberfeld, Welsch, & Hecht, 2018). However, such color manipulations are difficult to control with exactness, and it is therefore possible that the user's perceptual experience may be altered.…”
