It depends on the field:
Pastel tones of blue or green, grey or brown for dressing. Always avoid black and pink togheter
Orange for designed industrial objects, like lamps etc...
White for old cars and motorcycles, I mean from the sixties or earlier. White is also good for wall plastering, but other than in these two cases I dislike it.
Black is sometimes nice for girls' dresses, but transparent is also good
I also like saturated yellow in general, regardless of the application.
Right now I'm asking myself why am I sitting here at quarter to one in the morning writing detailed explanations about my colour preferences...
