This research was aimed to investigate the unattractive colors for plain cigarette packaging design. Each 60 males and 60 females were equally divided in to two groups as smoker and non-smoker. For the first part, the subjects were asked to adjust the color in order to find average color values of each unattractive brown, olive-green, gray, purple. In the second part, six mockups of plain cigarette package were made in different background color(4 unattractive colors, black and white).The effectiveness of each color on plain cigarette packaging was compared. We found that purple was the most unattractive background color. However, brown or olive green were recommended to be the background color of plain cigarette packaging.

This study aimed at investigating the color transition of a betacyanin dye-based RSi label that used an extracted-dye from red dragon fruit peels using a solvent soaking method. They were performed to a thin film with different ratios of a dye and a film former(2.5:1.0 and 5.0:1.0 parts).After that, they were tested with differences in temperature and curing time. The results found that the RSi labels revealed an original pink color and it could change to orange-brown which depended on the temperature and time. Moreover, some properties of the RSi label, the rates of color transition and the possible use as a dye for applying in intelligent packaging technology as well as an indicator ink were also reported.

This research aimed to develop the Computer Assisted Instruction, CAI for vocabularies lesson for the low vision children around grade 5-6 in elementary school. The low vision children are many kinds, i.e. narrow of visual field, too nearside etc. When working with low vision children, it is important to remember that they have the potential to learn to use their vision in a more efficient way. How teachers should do to help them reach their maximum level of visual efficiency? Teachers and other professionals working with these children have to provide the necessary instruction and environmental modifications to help students maximize their visual ability, develop a positive self-image and greater independence in the classroom and the community. CAI is one tool to help to improve the visual ability.

Braille writing system is one of the ways the visual impairment disabled people use to communicate with normal people, thus this research has an objective to study the influence of the thickness of the Screen ink on the perceptive capability of the visual impairment disabled people. Parallelly, this research also aims to check the quality (color difference before heat and after heat) of screen printing that is proper for printing Braille language or not. We also checked the recognized of image and Braille letters with the real defective peoples. The result showed that the screen printing was proper to use for making Braille media. The highest thickness showed good recognition. Heat the emboss the Braille affected to color change quite much.

The good looking of photography is important in the advertisement, especially, the healthy skin of a model. This research aimed to use the 20 color filters of pink, orange and brown tones to improve the color skin of the model. A tan skin model was taken photo through those color filters. Thirty subjects were asked to rate the healthy appearance of the model. The rate score was ranged from 0 (unhealthy) to 7 (healthy). The result showed that the photograph taken through pink tone color filter give healthier skin impression.

This research aimed to investigate the influence of background color of silver jewelry advertising on purchasing decision. We took the photo of the silver product pasted on the flannel cloths which was eight colors different of background; red, green, blue, cyan, magenta, yellow, black and white. The observers were asked to assess the impression of luxury, reality, and purchasing decision with the sematic difference scales. The result showed the red background gave the highest scores for the impression of reality and purchasing decision. However, highest score for luxury appearance was obtained in case of black background.

In Japanese Heian era layered (Kasane) color was used for lady’s kimono. A thin silk was worn on colorful kimono to bring forth different color to people. In this experiment we investigated the layered color by using tissue instead of silk. Ten colors were printed on papers as stimuli and a commercially available tissue was placed on the papers. A subject judged the color by using the elementary color naming method. Five tissue conditions were prepared, no tissue, one sheet of tissue, two, three and four. Haze values were 0, 77, 89, 90, and 92, respectively. Ten subjects with normal color vision participated. Results showed no apparent hue change with increase of number of tissue but amount of chromaticness reduced.

Skin color was measured for 100 Thai male and 100 Thai female with a spectrophotometer to make database of Thai skin color. The average a* was 8.8, and b*=15.9 from female subjects and a*=9.0 and b*=16.9 from male subjects, showing skin color of male is slightly redder than that of female. Lightness L* was also measured and it was L*=56.8 ranging from 47 to 63 in female and L*=53.9 ranging from 41 to 63 from male, indicating slightly lighter in female. The data were compared with Garnier skin color scale which is popular in Thailand to sort out skin color to “dark”, “tan”, and “white”. The color scale, did not overlap with Thai skin color at all.

The present paper investigates the influence of glare on the color appearance of objects by simulating a tunnel in a laboratory. Twenty fluorescent lamps were placed in both sides of a simulated tunnel entrance and the strength of glare was changed by lighting various number of the lamps. Inside the tunnel a colored test patch was presented for a short time to a subject staying outset at 3 m distance. The subject named the color of the patch by 11 basic colors wearing the cataract experiencing goggles. Without glare and without goggles a subject identified 20 test patches as green, for example, but the number reduced to only one patch when the glare lamps were increased to 40 lamps.

The research is to relate aroma to color. Five aromas of flavor, jasmine, ylang-ylang, white plumeria, lotus, and moke, were adopted. Observer was given moist cotton by aroma and then he/she chose a hue on a hue ring sheet of Munsell Book of Color. 50 subjects participated in the experiment. The results showed that the hue chosen for aromas by largest number of subjects were: 5Y for lotus, 5RP for ylang-ylang, 5GY for moke, 10Y for white plumeria and 5PB for jasmine. Through the experiment we can say that aroma can be represented by colors, but it is desirable to obtain data from more subjects than the present 50 subjects.

Color of lips and skin of 100 Thai female students were measured with Konica Minolta Spectrophotometer CM512m3A. L* of lips color more or less stayed constant and distribution of 100 subjects covered a wide range of a*. L* of skin was always larger than that of lips, the averaged L*of skin being 56.5 and that of lips being 43.1. There was found no correlation between a* and a* or b* and b* in skin neither in lips. Spectral reflectance curves of skin and lips were compared among three examples of subjects and a deeper dip at around 560 nm due to melanin in lips than skin was evident in s white and tan skin. Lips colors were darker and redder in lips than in skin.

This research is to show that even with a 2D picture the chromatic adaptation to illumination can occur if the 2D picture is perceived 3D space. Pungrassamee et. al. (2015) showed that the chromatic adaptation took place when window size was large, and subject can recognize the information in the test room. This phenomenon was reproduced by 2D pictures with a help of D-up viewer which change 2D picture to 3D scene. The pictures were shown on a display and subjects observed them through a D-up viewer to judge the color appearance by the elementary color naming method. It was confirmed that the color appearance was exactly same as those observed in the real two rooms case.

This research aimed to investigate the technique of taking photograph in case of adjusting opposite direction of color temperature of color illumination. A room was illuminated by seven colors illuminants; red, yellow, green, blue, magenta, cyan and white. Then took photograph under white balance setting in 5 differences; 5500K, 6000K, 6500K, 7000K, and 7500K. The photographs printed on the semigloss paper and measured the color of photograph compared with the color of the real scene. The research showed that the setting white balance at 6500K gave the almost same color of the real scene.
