When there is light, everything is visible. I decompose the fundamental element in the visual world to let the invisible become visible. It is a process deconstructing light. I project a white source of light on a surface while using prism and some moving images to "deconstruct" it. "White" is not an independent colour. It is a mixture of colour in the visible spectrum that is composed of the primary colour red, green and blue. Through refraction of light, I separated the white source with the three primary colours to rainbow light using a prism. After that, I took away green light from white light, leaving a mixture of red and blue light. Without green, the light source gradually reflects a new colour called magenta, hence the 'rainbow' becomes a 'duo-coloured rainbow'. Eventually, I erased red from magenta. The line results in pure blue colour. As blue is a primary coloured light that cannot be further decomposed by the prism, it appeared the ultimate light source in a monochromatic 'rainbow' colour.
