There's a song I've been a fan of for quite some time, Blue on Black, by Kenny Wayne Shepherd. I've even blogged about it in the way past. That's 2008, so it's been a while.
Hey, blue on black, tears on a river
A push on a shove, it don't mean much
Joker on Jack, match on a fire
Cold on ice, a dead man's touch
Whisper on a scream doesn't change a thing
Doesn't bring you back
Blue on black
The essential meaning is if you mix blue color into black, you get black. It's a metaphor for futility and pointlessness. As so many songs are, this song is about loss. One reason I love it is that you can pretty much hear every word as it's sung, and the lyrics are coherent.
