How can shadow have colour?
Mixing colour is different to mixing colour of light.
Mixing Red + Blue + Yellow colour creates Black colour. While mixing Red Light+ Blue Light + Green Light creates white light.
Looking from afar, 3 coloured light create what appear to be a normal white light.
What is SHADOW?
Shadow happens at the absent of light. When you are standing at a white light your shadow on the ground is black, because you are blocking all sort of light.
In this installation, we use 3 light colours to create a white light.When you are blocking one light bulb, your shadow lacks only that colour. The colour light from the other two bulbs can still cast on the ground. When you are blocking the green light your shadow on the ground still have red and blue light shining on it, making your shadow appear to have colour.
