Abstract This study aims to explore the influence of different light color temperatures and lighting illuminances on two kinds of crafts regarding touch motivation, preference, and product evaluation. A total of 40 subjects are recruited in this study. The independent variables include lighting color temperature (3500 K, 4500 K, and 5500 K) and illuminance (500 lx, 1000 lx, 1500 lx, and 2000 lx), and three different kinds of dependent variables are measured, including motivation to touch, prefer‑ ence, and 10 product evaluation questions, where each is ranked on a five point scale. The experimental results show that a pottery teapot is suitable for 3500 K at 1000 lx and a silver teapot is suitable for 4500 K at 1500 lx, while a color temperature of 5500 K or illuminance of 500 lx produces the lowest touch motivation and preference. The results of multiple regression analysis show that, if the lighting illuminance can improve viewers’ preference for the sample or show good touch on the surface, then their touch motivation will be stronger. The findings of this study can provide insight into the motivation of touch, and further provide some guidelines and recommendations regarding display lighting, in order to increase the com‑ petitive advantages of works.

1 Introduction 1.1 The effect of lighting Light sources not only meet people’s physiological needs for illumination, they also have great impact on people’s emotions, behaviors, spirit, and other aspects (Chen and Lin 2015; Li 2016; Manav 2007). Designers often use various lighting methods and techniques to change the light–dark contrast of a space, stimulate the visual senses of viewers, and then, produce various visual perception situations of the space to emphasize the nature and purpose of space and products. Illuminance and color temperature are the two main fac‑ tors that influence the lighting effect. Navvab (2002) com‑ pared the ability to recognize written characters under four conditions of two color temperatures (3500 K, 7500 K) and * Chih‑Long Lin [email protected] 1

two illuminances (7 lx, 120 lx), and the results showed that operation performance is significantly higher under 7500 K color temperature regardless of low or high illuminance. Mayr et al. (2013) examined two kinds of light sources (fluorescent lamp, halogen lamp) and illuminance (70 lx, 800 lx) in color recognition and paper text proofreading, and their results noted that a halogen lamp with 800 lx illu‑ minance is the best in both operations. The reason may be that a halogen lam
