That's good. Although that's a bit wrong. You can't take a monochrome image and add colour just by adjusting the contrast. I'm also not sure you can say it was "recorded" at all if it was broadcast directly, but that's a language question.

I believe the contrast adjustment was likely to get rid of any unwanted shades of grey before colouring the two extremes.

  I suspect 'coloring the two extremes' involves something more like 'wiring the luminance signal up to the chroma'. Again, try not to think digital. This isn't photoshop, this is signal processing.

    Or it could be a filter over the camera lens.

      Once you have a mostly Black, and White (with no greys) image - it's relatively simple via basic electronics to colour replace those with alternate colours - much like the old analogue chromakey 'blue-screen' techniques.
