Agree with carrieandjimh, You will need to connect the two colors through prints on pillows, curtains, rug etc. Can you post a pic of the sofa and wall color so we can see what we're talking about here? Thx.

Wish i found this Q &A before. So many beautiful people advising and sharing here! I am Repainting Tropical Queenslander with dark red and orangy timber floors and this thread is so helpful. I painted Whisper white and it is throwing so much Green it makes me so sad I am going to repaint. I get loads of tropical sun in the north facing - with eastern morning sunlight. Was just about to go and buy Natural White just to cover it. Do you think it will be too dull/warm a colour. I do like a fresh feel and contrasting with vivid white decorative trims. The whisper white looks nice For a while in the morning while the morning sunlight throws read up onto it but then it returns to a green

You may use a specific light in the grey on the wall were there are two windows. While the other wall with a long slim window has a wall feature design. There are numerous features to use, with the intension that it would be on the same colour contrast. As was mentioned that the blinds would be great sprayed though in a colour that will go with the walls colour and design. Need to be a balance in the colours for both walls and the blinds. You may use one wall with wallpaper feature if you prefer. I have found a site that may assist you with the design of your choice. http://colorhunter.com/; http://www.resene.com.au/wallpaper/#

Your floor and other wall colours are great but Red (orange), black and white are very harsh together, the wall cabinets either side of the range hood have been badly installed, they should have been built to the ceiling. My suggestion is because the kitchen is small, I would remove the cabinets either side of the range hood and then run a row of white cabinets across above the sink to the end of the bench top. Paint the walls white or a soft grey, the range then becomes a stand alone feature. You didn't mention what the splash back material is but I would consider a clear mirror splash back along behind the sink and up to the base of the new white cabinets so that you're not just looking at a wall. cheers
