"Entry is open to all ages and we encourage everyone from the very young to the very old to submit their work."
Artists have the opportunity to sell their work at the exhibition with the proviso that a suggested 30 per cent of the sale price is donated to the Green Party.
Whanganui Green Party candidate Nicola Patrick says she hopes to see a really good range of multimedia entries.
"People might think they have to go to a lot of trouble to create something but they may be surprised to find they already have something they have made from recycled materials."
Ms Patrick said the concept was a bit of a spoof on the erotic romance novel Fifty Shades of Grey by British author E. L. James.
"It seems like a good number to aim for and it will be great if we can get 50 shades of green."
Entry forms are available online from the Shades of Green Art Exhibition Facebook Page.
