This is a photo I took in a museum named 「At the Moment」. The work in the photo is composed by a set of three primary colors of lights: red, green and blue, and a white curtain. From the photo, you can see that the three colors of lights were separated at first, and they formed scattered color blocks of red, blue and green on the white curtain. It’s just that these color blocks create new colors in the place where they are touching one another. Green and blue cross into cyan, where red and blue mix produces red, and there is a bit of yellow between red and green. In addition, a human-shaped shadow appears on the photo. People stand in front of the white curtain, blocking the light from spreading in a straight line, forming a black shadow on the curtain. The figure is based on the principle of using the three primary colors of light as a background to form a slightly cyberpunk-style work.
