Color is a spectrum of visible sunlight absorbed on the earth's surface, and it is basic energy which maintains the ecosystem of the earth, including humans. About 41% of solar radiation absorbed by the earth is visible radiation, and maximum energy is obtained from the dark blue wavelength of about 0.47μm. So, an ecosystem has the flow of energy originated from solar energy, which leads to the cycle of materials. That is, photosynthesis-the process of storing solar energy into chemical energy of organic molecules-is the first stage of energy flow in most biological world. However, photosynthesis is the process that chlorophyll in plants absorbs mainly blue and red wavelengths from visible light, and synthesizes carbohydrates. Thus, a spectrum of visible light, which is perceived by humans as colors, works as direct energy in an ecosystem. This study is conducted to investigate a principle of color harmony derived from environmental colors surrounding humans, from the aspects of physics and biology, not from the aspect of emotion. From the perspective of energy balance, the color system of the nature, which changes depending on latitudes and seasons, is investigated and analyzed by using a tool, the NCS(Natural Color System). Additionally, to apply such principle of color balance to a space constructed by humans, the plans of color and nuance, various color plans depending on time and space, as well as the color plans supporting human behaviors, are suggested from the perspective of energy balance. |
