The latest lighting fad?

Dunno, but they seem to be everywhere ...

Can you give an example to look out for?

However, I doubt they'd show heaters unless part of the 'plot'.

I'm guessing the OP is thinking of those huge searchlights that
are more for decoration than illumination.

Possibly something like this:

Ah, now I understand. I thought you were meaning pure red lights as in the
colour of traffic lights or car brake lights. These are incandescent "white"
lights with a warmer colour temperature than the lights used to illuminate
the set.

I have no idea what the significance of the fad is. The first one is a
theatrical lamp, complete with barn doors to restrict the beam of light. The
other two don't even have that vague relevance to a stage setting.

That is a pretty standard studio hard source light - the barn doors being
the give away. It is run right down on its dimmer and just used as a
pretty prop. It's not really doing any lighting as such. It is 'red' like
any other tungsten lamp dimmed right down.

Also looks like it is a background pic keyed into place, by the blue
fringing round the artist's head and shoulders. Spill from a blue screen.
Or just very odd back lighting.

Yes - all just set dressing. No practical use involved.

It looks more like back lighting with a blue light rather than poor
Chromakey, though I suppose if he was very close to a blue screen or it was
very brightly over-lit, you might get spill.

As a matter of interest, why is it that they used to use blue backgrounds
and keying for Chromakey but nowadays almost always use green? I thought
that blue was chosen because it was the least likely primary to be contained
in the foreground subject, and the most diammetrically opposite to flesh
tones which are the absolute worst thing that they want to cause false
triggering.

The use of blue was a throw back to 'film chromakey', which I think was
the easiest colour to separate out in that process.

Green is chosen for contemporary video chromakey, because it constitutes
a higher proportion of the signal, requires less illumination, and
therefore generates a better 'mask'.

I was told in BBC training that blue was chosen from RGB because there was
less of it in flesh tones. So gave the best separation to faces.

therefore generates a better 'mask'.

I thought green was the original colour used in proper film?

I thought the film had used green (or in some cases, sodium yellow) for
along time as the matte-out colour, and that TV had gradually changed from
blue to green as so to fall into line with film practice.
