Concept behind Sky series by Zhao Zhao:

‘I first began the Sky series in 2009 contemplating on the permanent pollution of Beijing where the sky is rarely blue. As I was executing it, I instinctively thought about the real sky, wanting to reference some form of flow... but photographs are static. During that time, I could not see what the sky really looked like. For things I haven’t seen in a long time, I need to draw from my own memory and subconscious to depict them. In a way, behind the Sky series is my fabrication of the sky.
I was returning indoors to complete a monochrome depiction of something from the outdoors. It was not reliant on photographs, or on the range of colours. I used Prussian and Rembrandt blue. This is a rather forgiving colour, which is why I say it is like ink. I used its two extremes, black and white, as well as its intermediary hue, blue. I grasped the different shades and hues that emerged between. I also constrained my own abilities as much as possible.’
