1 Introduction

When it comes to product design, some factors such as the art design and colors of digital technology products should be considered as a designer should gain control over the design method and creative thinking. Obviously, the colors of a technology product will have an effect on human emotion and feelings, as well as their desire to purchase the products. This study should carefully examine the color phase of the product, its brightness and Chroma when designing the colors for the product. Different colors will result in a variety of mental awareness. The color blue represents the color awareness of comfort and technology. For example, HP, Facebook, or companies like Intel all uses the blue element for design to highlight people’s recognition of a feeling of high technology. The color red represents the color awareness of activeness and high-spirited nature. For example, Coca-Cola and Canon both use the red logo to show a mental color of passion. The color green represents nature, peace, and happiness. Android, Acer, and Starbucks all use the color green to create a feeling of happiness.

The color determines emotional factors for the product, and attracts the consumer’s attention. The proper color match for the product design is a critical factor of the emotion of colors. This study adopts the color match of portable Bluetooth speakers by incorporating two colors for the color match to convey the color awareness of relaxing, happiness, and technology. The color specification used for this product adopts the professional color sample introduced by Pantone. The experiment adopts 12 colors in total, including the color black, to match with 185 (red), 1495 (orange), 108 (yellow), 355 (green), 299 (blue), 251 (light purple), 430 (grey), and 730 (gold). The color grey is applied to match with 1655 (blood orange), 360 (light green), and 238 (purple). The color white is applied to match with 507 (metallic purple) to implement the study of color match.

This study mainly focuses on confirming the portable product, the Bluetooth speaker and its most popular proportion of the color match to adopt the color black or grey to match with other colors. It also focuses on the emotional features of a variety of color matches, and examines the most appropriate cultural and creative graphics. Last but not least, statistics show that the most popular size for the Bluetooth speaker offers the most appropriate colors, graphics, and size for product design. Therefore, the three objectives applied to this study can be described as follows:

  1. 1.

    Confirmation should be made to determine the colors adopted by the most popular portable Bluetooth speaker through analysis to explore the emotional factors and emotional features of the colors applied to the product. Confirmation should be made to decide the emotional features of the color match used in a variety of color hues as well.

  2. 2.

    It’s suggested to sort out the ideal cultural and creative graphic according to the emotional features of the Bluetooth speaker in the course of cultural and creative graphic design to offer some ideas for the graphic design.

  3. 3.

    Run a statistical analysis on the study to explore the size of the portable Bluetooth speaker and its factors.

2 Literature Review

2.1 Cultural and Creative Graphic and Colors

Most of the portable products, Bluetooth speakers, found in the market would have at least 2–3 colors to choose from to decide the color match to offer a variety of choices to choose from based on the needs. The brightness, Chroma, and saturation applied can help distinguish the most common colors. The color black matches with gold, silver, and blue, which creates a gorgeous and quality look for the product. Black with low saturation matches with blue, red, yellow, and purple with high saturation. Such color creates a younger, high-spirited look for the product. The purpose of applying versatile color matching is to satisfy consumers with different preferences regarding a variety of colors through design. To snatch more market share, it was assumed that the consumers normally would prefer several colors for the color match, which is the research direction explored in this study. The color object designed in this study mainly focuses on the color black or grey to match with colors with higher brightness.

The cultural and creative graphics used in this study are based on the graphics of traditional Chinese culture. The Chinese elements applied can be considered as an art format to exhibit the approach. The Chinese style mostly applied to the study contains Mosaics, turf, wall paintings, and paper cut graphics. The portable product, a Bluetooth speaker, applied to this study normally would be put in any easy-to-reach place. Some basic graphics such as the simple five graphics including flames, dragon-shapes, and cloud-shapes are also incorporated into the cultural and creative graphic experiment for the product (Fig. 1).

2.2 Semantic Differential Technique

At present the commonly used color effect test method for the semantic differential technique, will describe the words of things or phenomena to be summarized into a standardized scale table, this word must have a common feeling, meaning to be concise and clear, and there are objective standards. Apply to the color scheme, the emotional language and color changes together, the production of Color Image Scale, according to set the color performance, rational, objective to find the appropriate color image.

The color image scale used in the semantic difference analysis can usually be divided into three types: cross type, contrast type and multi-direction type.

The color of the research product color design, the use of contrast color image scale, analysis of color psychological effects test is expected to be emotional, rational, gorgeous, simple, beautiful, ugly, happy, solemn, advanced, low, beautiful, weak, bright, Technology, local, etc., a total of 8 kinds of psychological tests and 12 kinds of color (Figs. 2 and 3).

2.3 Likert Scale

Likert scale is a measure of psychological response, often used in questionnaires, is currently used in the questionnaire survey. When the quiz answered the questionnaires, the direct response to the questionnaire items of the same level of recognition. The color of the pattern of this study will use the Likert scale to count and analyze.

The scale is the most commonly used one of the scoring scale, and the items of the same construct are scored in a lump sum. It was by the American social psychologist Li Kete in 1932 in the original total scale based on the improvement made. The scale consists of a set of statements, each statement has “very agree”, “consent”, “ordinary”, “do not agree”, “very disagree” five answers, respectively, as 1, 2, 3, 4, 5, or another seven scales, the total score of each respondents is his sum of the scores on the answer to each question, the total score can explain his attitude or her in this A different state on a scale. The advantages are easy to design; the use of a wider range than other scales can be used to measure some of the multidimensional complex concepts or attitudes that some other scales can not measure. In this study, the color and pattern of the product experiment, with seven scales for the measurement unit to obtain the data more objective and credibility (Fig. 4).

3 Research Method

First of all, this study focuses on the mental response to the color of a portable Bluetooth speaker. It examines the most appropriate color for the product by using the Semantic Differential Technique (SDT). The colors introduced by Pantone serve as its foundation. 12 colors applied to the color match were used to run a mental test by acquiring the most popular colors for a statistical study to analyze the best result of visual effect for colors. Next, the portable Bluetooth speaker applied to the design can constitute 60 experiments together with 5 cultural and creative graphics and 12 sets of color matches. The Likert Scale applied here is used for statistical data and analysis. It allows the subject to choose the most appropriate totem and color match approach for colors. Ultimately, the survey shows that according to the statistics, the size of the portable Bluetooth speaker is the most popular size used for the experiment. Then statistics are run on the data and analysis.

3.1 Design of Experiment on the Color Match for the Product

First, decide the main topic for this study and its scope. Next, carefully decide the research questions through planning. After the research destination is settled, collect some literature about the design of the portable Bluetooth speaker and its color aesthetics. A discussion should be held to run an analysis so that it can serve as the foundation for future study on the questionnaire survey. Bluetooth speakers found in the market are adopted and used as the research direction for this survey. The object of this survey is colors for design, graphics, and size, which can be the targets to analyze in this study. It is estimated that a total of 30 samples would be collected, and the design elements would serve as the subject matter of this study.

In the first experiment, we selected 12 kinds of PANTONE colors to experiment with the emotional factors of various colors, and evaluated the color emotion of the product to evaluate the most popular portable Bluetooth speaker color. Before the experiment, observe the commonly used colors of the commercially available Bluetooth speakers. (Red), 1495 (orange), 108 (yellow), 355 (green), 299 (blue), 251 (shallow), black and white, as the base color, Purple (blue), 730 (gold), 1655 (orange), 360 (light green) with 238 (purple) and 507 (metal violet), and color experiments from the PANTONE color system.

30 subjects were asked to choose one of the questionnaires, to sensibility, to sensibility, gorgeous, beautiful, happy, senior, beautiful, bright, science and technology, rational, simple, ugly, solemn, low, weak, gray For the color psychological test target, and to observe the most popular portable Bluetooth speaker color matching (Figs. 5 and 6).

3.2 Design of Experiment on the Cultural and Creative Graphic

The cultural and creative graphics in Chinese style are applied to provide the experimental stimulus. It combines each color match with the stimulus of graphics. The graphics are contained in a particular surrounding under control. The computer screen shows a unified color grey as its background color. After a combination with the graphics, the product is placed on the screen to be modified using Adobe Illustrator and Adobe Photoshop. The design graphic of the product used here can be taken as the basic image for the study. The experiment stimulus was formed naturally by adjusting the colors and graphics of the product.

In each design of the composition, from the PANTONE 12 colors plus 5 kinds of patterns, color after a total of 60 kinds of color and pattern design. The method used in this study, first, requires the subject to view the digital image projected onto the display. The subject scored the color of the color and the desired image, and finally, the color of the image appearance and the respondent’s response were compared.

A total of 30 subjects were tested, 12 males and 18 females participated in the study. The age of these subjects from 18 to 30 years old, the experimental object is college students and graduate students. Experiment to do not like, do not like, do not like a little, Ordinary, slightly like, like, very much like a total of 7 scales, and to design the 12 kinds of colors to carry out psychological reactions, color emotional characteristics are calculated by calculating their average (Figs. 7 and 8).

Statistics show that according to the research results, the portable product, a Bluetooth speaker, with a size of 35 × 35 × 70 mm is the most popular size used outdoors.

5 Discussion and Conclusion

This study focuses on the color black, grey, and white together with other colors. An implementation on the study is done by incorporating the emotional features of each color match. Three main goals can be applied to this study using three experiments to practice. First of all, using Semantic Differential Technique (SDT), this study adopts aesthetics and quality to serve as the emotional factors of the color mental test, and to evaluate the color emotion for the product. Research results show that a report on the color match found that the color black with orange is the most acceptable color match with aesthetics and quality compared to other colors. Secondly, a confirmation made to decide the cultural and creative graphic for the portable Bluetooth speaker has adopted the Likert Scale to run the statistics. Research results show that the Chinese-style flame graphic is the most popular one. Last but not least, the research result of the size for product design shows that the most popular and appropriate size for portable Bluetooth speaker is 35 × 35 × 70 mm. The research results of the colors, graphics, and size for product design would be rendered to the product design and design learning for reference.
