“…Such a design may unpremeditatedly help to reveal the influence of other contextual factors on colour preference, since it relatively weakens the impact of light when compared to the conditions where CCT differs. However, unlike colour fidelity, colour preference should not be restricted by a reference light source, since in many cases people actually want to choose a favorite light irrespective of the CCT 4,26,[33][34][35][36][37] . Secondly, the experimental object is also an important concern.…”

Colour preference of lighting is generally influenced by three kinds of contextual factors, which are the features of light, object and observer. In this study, a series of psychophysical experiments were conducted to investigate and compare the effect of certain factors on colour preference, including spectral power distribution of light, lighting application, observers' personal colour preference, regional cultural difference and gender difference. Certain LED lights with different correlated colour temperatures were used to illuminate a wide selection of objects. Participant response was quantified by a 7-point rating method or a 5-level ranking method. It was found that the preferred illumination for different objects exhibited a similar trend and the influence of light was significantly stronger than that of other factors. Therefore, we conclude that the light itself (rather than, for example, the objects that are viewed) is the most crucial factor for predicting which light, among several candidates with different CCTs, an observer will prefer. In addition, some of the gamut-based colour quality metrics correlated well with the participants' response, which corroborates the viewpoint that colour preference is strongly influenced by colour saturation. Moreover, the familiarity of the object affects the ratings for each experiment while the colour of the objects also influences colour preference.

“…The utilization of three types of LEDs that each emit a basic color, i.e. blue, green and red, can produce secondary and tertiary colors, covering almost all colors in everyday life [1,2]. Although the assessment of colors is still based on human feeling and senses, a quantitative analysis of light must use a quantitative analysis standard, such as the color space coordinates published by the Commission Internationale de l'Éclairage (CIE), from CIE 1931, CIE 1933 to CIE 1960 [3].…”

Abstract. In this study, a quantitative analysis was conducted based on the CIE 1931 color space to determine a number of color combinations of three LED (light emitting diode) light sources and three laser sources respectively. The light sources used in this research were three LEDs that emitted blue, green and red light, and three laser sources that also emitted blue, green and red light. The results of the color combinations of these light sources were captured using a spectrophotometer. The obtained light spectra were then analyzed using a set of color matching functions that was modified specially for the spectrophotometer used. This research produced a quantitative analysis of 26 color combinations from LED light sources and 7 color combinations from laser light sources. The results of the color combinations ranged from blue, cyan, yellow, orange and red to purple. Further development of the proposed method is still required to obtain more reliable quantitative analysis results.

“…2 Specifically, the study of Kruithof revealed the lower and upper illuminance thresholds for a range of CCT within which the observers find illumination as "pleasing." 3 Several studies [4][5][6][7][8][9][10][11][12][13] have been done to reexamine the findings of Kruithof's graph and some of them have been reported with inconsistent conclusions. 14,15 Among all the studies based on validation of Kruithof graph, two studies have found that CCT has no significant effect on ratings of pleasantness.…”

Colour of light modulates the appearance of displayed artifacts in exhibition.To understand the effect of light on appearance of paintings, few studies have experimented to establish a relation between pleasantness with the correlated colour temperature (CCT) of light. However, some studies have found that CCT has no significant effect on pleasant appearance of painting. Therefore, in this article, an experiment with a qualitative (questionnaire on semantic differential scale, N = 30) approach was designed to understand the effect of CCT on appearance of paintings exhibited under LED lights. The findings from the experimental result depict that the appearance of paintings changes due to different CCTs of LEDs having the same illuminance. In addition, the result reveals that for both mediums of paintings considered in this study, in comparison to warm white LED and artificial daylight LED, cool white LED has appeared to be more pleasant having moderately warm feelings to the viewers.
