The right answer: The person who said that is an idiot who is
just focused on color and not on the possible symbolism. If you
actually read the lyrics, you'd know all the people who say it is
about abuse are, well, wrong.
Here is what it is really about:
Some mistakes/betrayals can't be forgiven, and any attempts to
make it better are meaningless because the original offense drowns
out any attempt to make it better. That is what the song is about,
and it states it, in the song, outside of the metaphors even. It
doesn't specify what the mistake/betrayal is, but I'm assuming the
subject of the song was cheated on by other cues in the song.
No, it is not about abuse, just because someone mentions the
colors black and blue does not mean they are talking about bruises.
Listen to the rest of the lyrics, Match on a fire. hmm a match
thrown on a fire is pretty POINTLESS, don't you think? Same goes
for tears on a river, and everything else mentioned. Try coloring
over a black marker with a blue marker. It's still black, the blue
changes nothing. Thus "blue on black . don't mean much" That is the
point of the title and the main refrain.
Geez people, don't be so literal. Don't they teach metaphors and
understanding them in schools anymore?
