**1. Introduction**

There are very few things that influence human behaviour, which affect their colour preferences as an important aspect of visual experience, such things could be website design, purchase of electronics or home appliances, and buying of personal thing like clothes, shoes and bags. Most people might not understand why they prefer some colors objects (**Figure 1**) to others due to this psychological or behavioural experiences demonstrated by most users when involved in certain activities from most scientific studies [1–3]. Of recent, these explanations have been speculated on how and why users prefer different colours maybe others more preferable than some. Sometimes, colour choices tend to originate from how they are conveyed to humans or users. Most colours attract users at first contact with the eyes while others simple discourage or feel less attractive to approach. Hassenzahl [4] suggested that colour preferences are subconsciously ignited or planted into human memory on a neutral responsive base that are interpreted as some form of support for the biological adaptive theory of colour preferences. The color planted in human memory improves the performance on evolutionary biological phenomena such as how tentative users find some dresses in red more attractive to wear than dresses in brown or green. So to optimise, genetics tune this to behavioural

substantial perceptions which resulted in choices of colours for objects rather than colours of their background and free of their original context.

approaches that exist to assess the visual aesthetics of the interactive products presented to users, one of which involve the selected results of two kinds of studies reported in [10], that used the dimension of classical aesthetics proposed by the research work. This is to properly present the relation of perceived visual aesthetics to the perception of the usability, emotional response and consequences of user experience [4, 15, 16]. Research work on overall preference and satisfaction from assess replication to evaluating user reaction (**Figure 2**), as clearly stated steps torwards control service customisation to aesthetics and object identification.

Also, it has been argued that the components associated with usability, such as satisfaction, effectiveness, and efficiency, are never a sole forecast for user experience [17, 18]. The inclusion and assessment of hedonic and pragmatic features regarding user experience technology study about interaction based on pleasure, engagement, pleasure, fun, and games. For mobile devices, it is clear that they have a set of features such as GPS, touch screen and cameras over games consoles that allows for different mode of interactions. Few research as [4, 10, 19–21] stated that aesthetics has demonstrated a positive effect on user perception on mobile system's ease of use, for enjoyment and usefulness. However, the impact of the degree of visual aesthetic quality, which could be high or low on perceived usability is not clear. [22–25] conducted an experiment in the e-commerce domain to explore the hedonic and practical motivation and engagement including both functional and pleasurable aspects of user experience and the hedonic qualities of the colour object properties such as practical and entertaining concepts together with efficiency, functional attributes, cost and influential user engagement. Consequently, there are different kinds of study that have been conducted to assess visual aesthetics and user experience in areas of online news, video games and web surfing. These areas examine the quality of information interactions from users' perspectives. By contrast, perceived aesthetics, usability and focused attention emerged to be typically different from all other visual experience study. Some papers [12, 18] made recommendation on how to make use of fewer constructs in user experience scale on visual aesthetics. Hence, this scale was reduced to four factors which include aesthetics, reward, focused attention and perceived usability. Aesthetics as defined by [19, 20, 26], as the sensuous qualities, the experiences and the emotions that occur while interacting with a colour objects. Visual aesthetics refers to the
