Lace Sensors are very definitely available in black.

I've considered putting them on my Mustang, but I opted for American Standards, due to a little more bass, which I liked.
Sensors are great. There's no 60Hz hum, they don't drag your strings (thus helping intonation), and they have this very lively tone that makes chords jump out. I owned a Strat Plus with gold Sensors and it was niiiice.
