There is a whole different side to this, at least in my case. I am of a pail skin type and so on that makes any bright color stand out horribley when I wear it. I just have to be very careful about what colors I'm wearing which happens to exclude all the bright oranges and red of tartan. I can't mix real brown and real black, not charcoal, at all and that excludes all these day wear/ evening wear rules for me.
