Was watching Detective Story short of the Animatrix since the new short is like a week away. Some thoughts came to attention that thought would make a good discussion.

When the detective lights his lighter... is that a gliche in the Matrix since the rest is black & white? Would explain why he didn't light his cig or the Agents stopped? Why else would the flame be coloured? Would like other opinions or confirmation on this.
Perhaps no mention and just something to keep focus on. Or that the flame was his life and it goes out!

Ideas?
