Incense, black background, off-camera flash.

       It would appear that you can e-mail the photographer who took the
image and ask him/her what was done.

       It is not clear what you are asking, though. The photo appears to be
lit only by a flash or strobe unit, but from the side. This would need only  
the strobe and a cord to use it off of the camera hot shoe.

       I suspect the two different colors in the photo came from two
different types of smoke, which makes me think it's from a candle - one
color from burning wax, another from the cotton wick. That's only a guess.

       There is nothing that "disturbs" the white-balance of film, but light
that is not within the color temperature range of about 5000-5500 Kelvin
(usually just "K") will not appear white, and will make your subject change
color.

       You can use many kinds of lights, and add an appropriate filter to
the lens to compensate for the color they provide. Getting a perfect
balance can be tricky, though. For incandescent lights, you'll need a blue
filter, because their light is too yellow. For fluorescent lights, you'll
need a magenta filter to balance their green light.

At a guess, I expect this is a studio shot. Strobes against the smoke in
front of a back background.
