Yellow with a black border is the
only proper way to present subtitles. White subtitles are unreadable during bright scenes; and the damned subtitles get smaller every year, making it impossible for people with failing eyesight (like me) to read them from across a room.
But yeah, makers of subtitles seem to be opting for tiny white-only fonts these days. That's all right, if you want to kiss a computing-system's monitor screen; but if you're viewing is done via a television receiver it's torture. So as much as I dislike dubbed films and prefer subtitled ones, I'm having to either opt for dubbing or sit in a chair right in front of the television-receiver screen.
