Color is considered to have the ability to manipulate several aspects such as height, depth, and the thermal atmosphere of the room. As one aspect that can be manipulated by color, thermal becomes an important element in the design because it will have a direct effect on comfort which in turn will have an impact on health and productivity. The relationship between color and thermal is judged to be related to the perception that some colors often symbolize or are associated with certain temperature conditions, such as red which is identical to hot and blue which is identical to cold. The effect of color on thermal assessment has potential as a strategy to achieve energy-efficient thermal comfort. Research related to the relationship between color and thermal is still a debate where some researchers say there is a relationship but others do not. Unfortunately, research in this area has not been able to fully explain the relationship between color and thermal. Important variables such as meaning or color perception were not tested further. The absence of research on this meaning resulted in previous research using only the initial hypothesis, the hue-heat hypothesis, which was not re-tested. In addition, aspects that go beyond convenience such as productivity have never been tested. Based on these problems, this study tries to discuss the meaning of color in a thermal context to further examine its relationship to thermal sensation and comfort and productivity. This research was conducted with two data collection methods, that are online questionnaires and experiments in the thermal chamaber. An online questionnaire will be distributed to collect data about the meaning or perception of color. In the experimental method, respondents are asked to feel a room that has been adjusted to the thermal conditions and the color of the room. Then, they will be asked to provide an assessment of sensation, thermal comfort, and visual comfort. In addition, respondents will also undergo a series of tests to assess their level of productivity. Based on these data, it was found that the thermal meaning of color is not entirely the same as that stated in the hue-heat hypothesis where purple, which has a wavelength close to blue, is considered a neutral color and tends to be warm. In addition, this study did not find a significant relationship between room color and thermal sensation and comfort. The findings that are different from previous studies are thought to be related to the low illumination value so that the color identification that occurs is worse than previous studies. A non-significant relationship was also found between room color and productivity. However, there is a tendency where colors that are considered visually uncomfortable actually have a better reaction value. These findings relate to arousal where in simple activities, high arousal will have a positive impact on productivity. The researcher suggests conducting further research with more respondents and better lighting conditioning so that the relationship between room color and thermal sensation can be studied better. Researchers recommend a minimum illumination of 350-400 lux as the standard illumination value regulated by SNI. Further research is deemed necessary to unlock the potential of using color to achieve low-energy thermal comfort
