Depends on the shade of yellow and circumstances. And what kind of clothes you're wearing. Yellow is a very picky and difficult color, not everyone can pull it out, specially wearing it on its own without other complimentary colors. Which is why some people will look plain horribly.

There's that choice, yes. But I wouldn't shut up if I had something bad or mean to tell them, so I don't see why I should shut up when saying something good, specially if it's true.
