I'd find an all white house terribly depressing, I think, but I do really love colour. I do agree that it's dependent on the style of the house, though.
Here we have pale chalky greyish pink (nearly white) in the living room, with multicoloured rug (predominantly dark red) and white sofas with either red or very dark pink throws. I love this room's colours. It feels airy but not cold, IYSWIM. We have stripped the floor boards in every room apart from the kitchen and bathroom and beige (boring) carpet up the stairs and on the landing.
Dining room/play room has a dado rail and is a lovely rich ochre up to that with pale cream (not magnolia, it actually has a hint of olivey green in it) above. Very warm and welcoming. We also have a very bright multicoloured stripy rug in here.
The hall and landing are just very plain pale cream/sand colour.
Kitchen is pale bluish grey, nice and cool to look at, with pale wood units and stainless steel cooker. The floor is slate and the counters are dark stone.
Upstairs, we have a very pale lavender/grey colour in our bedroom which is probably the least successful of the colours. It's a bit dull, tbh. I think I'd quite like to redo it in something a bit darker and cosier.
Spare bedroom has a rich magenta/purple up to the dado rail and v v v pale grey above it. I love this but it's quite a strong look and I don't know if I'd do it in a room that's used more frequently.
DD's bedroom is white with one bright red wall and a picture rail height alphabet running round the top of the white walls in crayon colours, blue, red, green and yellow.
The bathroom has very pale green tongue and groove on the non-tiled bits up to dado rail height and a pale sandy colour above. The floor is dull green rubber tiles and the wall tiles by the bath etc are white - like the ones you used to get in public lavatories. This is really successful as the green is nice and cool and the sandy colour adds a bit of warmth.
Er, that's quite exhaustive, isn't it?!
