It definitely looks like it has a filter on - even the white are not proper whites. It would look so much better with fresh white walls.
Whether you like the colour scheme or not, I think the matching clothes are interesting. My friend does this. Her colour scheme for the house (not the same as this and not so matching between rooms) is the same as clothes that suits her family and she buys them (young). It has the effect that even clothes that are strewn around on the furniture match and look good. I sometimes wish I had the patience to do something similar!
