Houses that can change colors
The exterior wall painting cycle often lasts for several years. The exterior color of the house tends to only change during renovations and renovations. My idea is to replace ordinary paint with a special painting material, which can change with the weather, season, day and night. Paint this kind of paint on the exterior wall of the house, and the house can change its color at any time.
As far as I know, there is currently a heat-sensitive material that can change color with temperature. The color of the material shows different colors in different temperature ranges, and this color change is reversible. Therefore, the characteristics of heat-sensitive materials can be used to design a house that can change with temperature by using heat-sensitive materials for exterior wall coatings. When the color of the house is no longer static, there is a sense of novelty every time you go home.
But this kind of material as exterior wall paint is susceptible to many factors and still needs to continue to develop. For example, its discoloration temperature range should be small, and the color difference between the two colors after discoloration is large. It should have good stability, not easily affected by the external environment, and not decompose under light and wet weather conditions.
