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.

What did you end up choosing Sanyukta? Would be interested in seeing what you chose to go with the greeny-white.

If you are keeping the rug, take the blue or pink out of it, and use that as paint colour. Only problem is I think the rug may be too small. We like to consider each room as a whole, can you post different views please? Leave out things you're not keeping in there.

To Modernise this without rendering or retiling the roof I would probably recommend to go darker with the trims. My top pick as a colour consultant would be Dulux's Domino for the trim. It will be a little bolder and create a more modern contemporary feel. You can see it pictured below as the trim. Obviously this house has painted their bricks in the shade "teahouse" however it will still look much better on your 1980s "peru" colour bricks!
