@Eva,
Ditto. I need colour. Grey is okay to wear, but not in a house, well, mine, at least. And I don't really like yellow, with or without the grey. Carib colours, mexicana colours, african colours, middle eastern - all yes, yes, yes. But it depends, doesn't it, on what you're doing - decorating a bedroom, a bathroom, a family room, or yourself... don't want it too lively to go to sleep, right?
I also like the cool blues, greens and whites together. Very crisp.
