“…The Kruskal–Wallis test and an independent t -test were used to analyse the data obtained from the experiment. Participants’ impulsiveness and arousal were defined as: high arousal (HA), faster reactions and lower error rate; low arousal (LA), slower reactions and higher error rate; high impulsiveness (HI), shorter response time and higher error rate; and low impulsiveness (LI), longer response time and lower error rate (all compared with the mean of the reference white colour background) [ 7 , 8 , 65 , 71 ].…”

“…Response time and error rate were the two main parameters measured during the experiments. The results of these tests were used to estimate the levels of arousal and impulsiveness shown by each participant, which can be used as an indirect way to understand how colour affects cognitive ability [ 7 , 8 , 65 ].…”

“…Colour is recognised as a ubiquitous visual design tool that is used with great effect beyond aesthetic considerations, with about 70–80% of visual information gained through colour [ 5 ]. Colour research has demonstrated the real-world design potential of colour and light on people’s arousal and impulsiveness, affecting their emotions and cognitive performance [ 6 , 7 , 8 ]. Reviewing existing literature helps establish three pillars of VR systems: immersion, presence, and interactivity [ 9 , 10 ].…”

“…Colour, as the core element of visual experience, has been proven in prior studies to positively affect people’s cognitive functions [ 8 , 37 ], perceptions [ 38 ], psychological and emotional reactions, and, ultimately [ 4 , 39 , 40 ], behavioural intentions [ 41 , 42 , 43 , 44 ]. The human eye and brain work together to translate light into colour.…”

This research explores the influence of colour on cognitive performance and intellectual abilities (i.e., logical and lateral thinking abilities and people’s attention to detail) in a conventional laboratory setting and an approximately identical virtual reality (VR) environment. Comparative experiments using psychological methods were carried out in both settings to explore the impact of immersive colour experience. This work builds on earlier studies that suggest that the VR environment enhances user experiences, with results evidencing that a considered approach to colour design can trigger a positive impact on user engagement. The experiments further evaluated the positive effects of immersive colour stimuli in VR by evaluating participants’ logical and lateral thinking abilities, as well as their attention to detail. Their response time and error rate when completing each psychometric test were recorded with different hue backgrounds in both environments. The data collected from participants reveal the differential impacts of colour between the reality setting using standard colour imaging displays and in an approximately identical VR environment. Analysis of the psychometric tests shows the differential influence of colours on logical and lateral thinking abilities and people’s attention to detail between the physical environment and the VR environment. Our findings add to the data demonstrating that a well-designed immersive colour experience in VR can trigger positive user engagement and, as explored in this study, improve cognitive performance. This again positions immersive colour experience as an important design tool to be fully considered in the creation of effective VR research and applications.
