They say there's an area of study called psychology of colors, which specifies the correlations between colors and our personality. Our life experiences can affect our choice of colors, and for instance, people who wear black are likely to have gonbe though sth traumatic (but on the other hand they might be fans of gothic music or black metal as well).
As for my favorite ones, I returned to the colors i used to like in my childhood, that is green and purple, after my teenage rebellion;) inspired by grunge when such colors where considered bimbo-like and genrally unacceptable. So we all suffered like Kurt Cobain, and wore dark and baggy clothes of unspecified color, or black was also a popular choice influenced also by predilection for the fin du siecle art period, when being black, mysterious, sickly pale and thin and always with a cig in your hand was most trendy.
Now I do like purple and green, and it doesn't matter if it's about clotthes or interior design. Of course i allow other colors as well.
