Hi anne, that's what I was originally thinking, my issue is what colour I use for the 'pop' :) I keep coming back to a teal/turquoise colour (it's one of my favourite colours!!), I love blues, purples, teal/turquoise - many on here have suggested yellow but I'm really not sure about it. Here in New Zealand we're in Autumn, nearing Winter so uncertain about the yellow. I found these cushions that I've fallen in love it, and wondering how I could make these work.. do I try teal and mustard together, as an interior designer suggested?

Please post several pictures of the room so we can help you

Sophisticated start. You could go with black and white photography, architectural pieces, art pieces- anything you love on the wall. Then, add pillows in the colors of the art work. If you want to stay more monochromatic, think in terms of textural interest, such as a shag area rug, pillows with seam detailing, etc.
