One day I went to a bar in Venice and felt very uncomfortable after drinking. At that time, I often became dizzy and couldn't see anything after drinking (so I stopped drinking in my later life). When I came out of the bar that day, I couldn't see anything. My friends brought me home. On the way, I saw a church with a light on the ceiling facing the entrance of the small canal. Then I can see things gradually.
The entrance of the church that I saw at that time was a cuboid, but I turned this space into a light bulb of a street lamp because it connects my mood in Venice. When I think of this light again, the image of a street lamp makes my feeling stronger, as the light in the dark.
The light in the bulb shines in the dark as if seeing hope. But outside the lamp is misty. Although it is bright, I can't see anything, just like my state of mind. I used red and blue because they are strong colours. They can emphasise the lamp, as well as the world inside and outside the lamp.
