Lovely print. I had a peacock feather print and I had a colour called glacier Grey behind. Think it was Wattyl . Again like your other walls it is a greenish grey but darker. I also had my prints on a charcoal wall..loved that too. As you said the picture ties in with the chairs and now it's not necessary to add more matching colours. I'd buy a couple of sample pots and paint large pieces of cardboard. With the other walls I would consider painting them in whisper white (Dulux) a very universal colour that ties in nicely with all colours.

Maybe try Asian/Balinese style business or look at pinterest: that will give you idea that you could take to a tradesman and get a quote on bespoke or if you have a male that is very handy some great ideas on that link. https://www.pinterest.com.au/pin/419679259009258301/
