In particular, immediately after sunset, it is called "Magic Hour", and furthermore, "Blue Hour", which has a strong indigo color and "Golden Hour", which dyes golden, are also expressed.　　　　　　　　　　Sunlight consists of seven colors: red, orange, yellow, green, blue, indigo, and purple, and is scattered by hitting dust and water vapor before it reaches our eyes after passing through the atmosphere layer.　　　　　　　　　　　　　　　　　　　　　　　　Morning and evening "burning" is a phenomenon that occurs when sunlight is lower than during the day and passes through a layer of atmosphere from the horizon for a long distance, so red light with long wavelengths reaches the eyes mainly. Is a fantastic and ephemeral natural phenomenon that changes depending on the amount of water vapor in the air, and changes color and shape every moment with the position of the sun, the movement and time of clouds.　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　From Tsukuda-ohashi Bridge, the color magic of once-in-a-lifetime encounter spreads over the sky of the waterside space.　　　　　　　　　Just by watching the river breeze transforming everyday scenery into a mysterious landscape, it seems that your heart will be washed away.
