Although I don't know if it is still there, the State Gallery of South Australia had an all yellow canvas, while the State Gallery of Western Australia once exhibited three canvases painted three different shades of car 'duco' paint. Whilst I'm not sure of the concept behind the yellow canvas the other three came with some spiel about "exploring the unique surface created by that type of paint".
I also have seen a virtually white canvas win first prize in a local art competition with the judges describing the work as "bold and confronting". No argument from me there. Many people criticised it and couldn't understand how it could even be called 'art'.
The point of this article is not to say that these canvases are not art but to ask the question why? Why would any artist want to produce such an artwork? At the end of the day, no matter what conceptual spin you put on the artwork, it still is just a canvas either not painted or painted entirely in one colour.
I'm not going to speculate on the possible thinking behind these works, nor am I going to justify their existence as a legitimate work of art. I'm simply going to leave the question open. Why would any artist want to produce such an artwork?
Unfortunately I'm still an emerging artist. My work has years to go before it becomes minimal enough to fully capture everything I have to express with a large blue canvas.
