A spectacular sky in your room. The color blue seems to have the power to make us feel refreshed and to improve our concentration. We have combined two kinds of blue, the sulfurized blue of silver foil and the deep indigo of Mizuhoshi pigments, to express a magnificent sky. Since foil is used, the way it shines changes depending on the way the light hits it. The expression changes considerably depending on the light, such as natural light coming in through a window during the daytime, or the light from a light source at night. We would be happy if you could display it in various places to find the position and angle where you can see your favorite color tone. In addition, the silver foil is coated to prevent discoloration, but the color of the foil will change little by little over time. We hope you will enjoy this change as well.
