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.

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.

I would love to see some photos of the house, interior and exterior. Where are you located and are there plenty of windows? Do you know what timber the floorboards are? If there is lots of direct sunlight onto the floorboards, this will reclect colour onto the walls so choosing the right "white" will be important. Did you want the one colour to go through the entire house? Are you wanting to keep the feel of the high ceilings or would you prefer to have them feel lower in some rooms? Regards, Bronwyn

Check the colour wheel for which cream e.g. yellowed pink based and go opposite colour,
