I like navy blue and various pastel colors. I also like the traditional black and white. Off-white is nice too.
I guess it really depends on what objects these colors are. When it comes to walls, I'd hate to see vivid blue, green, or pink walls, lol, but a delicate pastel blue or pink would be nice on a wall. Same with clothing - I don't like clothes with strong vivid colors; rather, I like some delicate coloring, or dark coloring alltogether, like navy blue or black.
Well.. my fav color used to be blue.
But now I just love so many different colors that I don't really have a single fav any longer.
I love blue, pink, red, black, white, some greens, lavender... etc etc
