Abstract
To attract customers and increase market opportunities, retailers frequently use lighting to highlight the color of their products. However, differences between perceived and actual color, triggered by display lighting, can motivate buyers to discard products after purchase. Few studies have been reported on differences in perceived color, caused by LEDs. This study focuses on two correlated color temperatures (2800 K, 4000 K) and illuminance levels (500 lx, 1500 lx) to create four LED-lit environments, and measures the differences in the color perceived by 20 observers on acrylonitrile–butadiene–styrene (ABS) plastics, with different surfaces, under these four environments. The results reveal that correlated color temperature results in larger perceived differences in color than illuminance, and the effects of LED light sources on green and yellow ABS plastic products are more obvious than their effects on red and blue products. One possible reason for this can be attributed to the visual sensitivity effect of human eyes. The results of this study can serve as a reference for designers fabricating ABS plastic products for practical lighting applications, and improving the role of LED lighting in sustainable development.
Highlights
The color of products and the lighting atmosphere are crucial aspects of design, with the aim of attracting customers and increasing market opportunities [1,2]
If display illumination is misused, it might cause unsustainable consumption behaviors [7,8]. Customers buy products they do not need more freely when influenced by certain lighting atmospheres in a store, a process known as over-consumption [8,9]
The experiment primarily controlled for correlated color temperature (CCT) and illuminance
Summary
The color of products and the lighting atmosphere are crucial aspects of design, with the aim of attracting customers and increasing market opportunities [1,2]. An even more critical factor is that, because the colors that consumers see in store are the mutually influenced result of the colors of products and lighting, as soon as consumers use the products, they may realize that the products’ colors are different from the color they perceived in the store This discrepancy leads to a low attractiveness level of the purchased product and an increased risk of the consumer discarding it [13,14]. To solve this problem, a balance should be found for display illumination in stores between creating a target atmosphere and reducing lighting-triggered color differences in products
