色彩的寒暖感知在日常生活中有著十分重要的作用，例如，在空間規劃、服裝設計等領域，都與人們對色彩的寒暖感知訊息息息相關。一般來說，色彩給人的寒暖感受主要取決於色相屬性。然而，這類的研究卻很少考慮色覺障礙者的情形，這一類型者者通常無法分辨某些特定色彩，因此造成生活上的困難或是與他人溝通的不便。若能夠了解色覺障礙者的寒暖感知，便可以建立更佳色覺友善的環境。本研究使用孟賽爾色票集作為色樣本，取色相5G作為參考色，依不同參考色的寒暖心理感知程度請受測者評價。本研究實驗的受測者共有42位，其中共有24位正常色覺、18位色覺障礙受測者；色覺障礙受測者當中，又分成P型色覺障礙 (紅色弱) 3名及 D型色覺障礙者 (綠色弱) 15名。實驗在微亮室中進行，並且將電子色票顯示在具有 Adobe RGB 色域的LCD顯示器上。在收集受測者的問卷、將各參考色的評價分數取平均值之後，繪製在CIE a*b*色彩平面上，產生寒暖評價等高線圖，用來以確認色相與寒暖程度的關係。另外，透過將色相角對寒暖評價分數擬合的正弦波圖型，近一步確認正常色覺者在不同彩度與寒暖程度的關係。在進一步分析不同色覺類型的寒暖色等高線圖及色相角對寒暖度的正弦波圖，也可了解色覺障礙者的寒暖程度感知情形。本研究希望在未來能夠減少色覺障礙者的溝通不便。

Perceiving the warmth of colors plays a crucial role in everyday life, such as in spatial planning and clothing design, as it is closely related to people's perception of colors. Generally, the warmth of colors is determined by their hue attributes. However, studies in this area often overlook individuals with color vision deficiencies. They are unable to distinguish certain specific colors, leading to difficulties in daily life and communication with others. Understanding the perception of warmth of colors in color vision deficiencies can help create more color vision-friendly environments. In this study, Munsell color chips were used as color samples, and the 5G hue was selected as the reference color. Participants were asked to evaluate the perceived degrees of warmth for different reference colors. The study involved a total of 42 participants, including 24 normal color vision observers and 18 color vision deficiency observers. Among the participants with color vision deficiencies, there were 3 with Protanopia and 15 with Deuteranopia. The experiment took place in a dim room, and electronic color chips were displayed on an Adobe RGB LCD monitor. After collecting the participants’ questionnaires, the rating scores for each reference color were collected. These mean scores were then plotted on the CIE a*b* plane to generate a contour map of warmth/coolness ratings, confirming the relationship between hue and perceived warmth. Additionally, by curve fitting the rating scores of color warmth to a sine wave pattern, the relationship between different chroma levels and degrees of warmth could be further examined. Through the analysis of warmth contour maps and ‘warmth vs. hue’ graphs for different types of color vision deficiencies, the perception of warmth in color vision deficiencies could be understood. With this research, the aim is to reduce communication difficulties for color vision deficiencies in the future.
