BBC World News from New Broadcasting House

You're missing my point. The studios you mention don't have a real newsroom backdrop, and don't employ coloured semitransparent acrylic panels to diffuse it. I'm talking about the red acrylic panels that are to the edges of the glass panels that show the newsroom and are used to diffuse the background at the edges of the set where it joins the glazing.

AFAIK you can't buy colour changing acrylic that can be DMX-controlled - so these are a fixed colour... (Though you can buy remote blinds that could achieve a similar result... At significant cost)

Its strange seeing the News Channel titles with the World branding after seeing the long titles for so long. And the newsroom backdrop looks so much more suitable for World rather than the London skyline.

The catwalk sequence doesn't really work with BBC world news compared to BBC News that definitely is done properly.

OK sorry, simple misunderstanding. I was suggesting that it would be possible to relight the catwalk area if you were to use for that for a programme eg. Business, etc.

Those panels above and below the big screens I am sure is burnt in red, add some white light to it and it becomes the red we know, whilst the one in C Is different you can tell there's a lighting tube in there so it can be lit to anything.

I think if someone did a mockup of Studio E with the Impact Colour Lighting theme you'll see it wouldn't work well against the predominantly red background in the newsroom.

I swear, every few months in here there's a spirited "Can The Lightboxes In Studio E Turn Other Colors" debate, with no convincing evidence either way to get everyone on a consensus.

Yet there is a photo on the previous page that shows the lightboxes coloured orange and yellow.
The brown colour coverings (diffusers?) are uniform across every single set in NBH and some we've seen in the nations and regions.
Most professional LED lighting that i've seen in images of NBH and elswhere seem to use RGB to create white.
All of the other LED lightboxes in all of the other NBH studios use RGB, so why would studio E be any different.
Having fixed red lights or white lights with a red plastic cover would likely create an inflexibility when it came to lighting the set for broadcast. Much easier to have RGB as the shade of red could be changed if it wasnt quite right.

My conclusion...
If lightboxes in Studio E are fixed to Red or White in the lighting computer they are still probably capable of producing every other colour.

However, the "yellow" section casts a red light on the white furniture in front of it, so the yellow and orange may well be the result of a dodgy phone camera.

The main advantage of using fixed colour LED strips is brightness. You get a lot more white light out of a while LED strip than an RGB one, which could be crucial in a space which can be affected by natural light from outside.

The lower lightbox on the catwalk is lit red in that image, but lit white in regular use. Yet still appeared to be brown when switched off in later images of the completed studio.

Even the white plastic covered ceiling ring has appeared crisp white, and a slightly pinky white in both E and C when compared to other white lightboxes in the same image.

Lack of evidence is not evidence, so i guess until an insider says otherwise it is a moot point.

My World News Stream picked today to take a dump so i guess i'll have to wait until midnight to watch it on the iPlayer.

But so far what i've seen of Newsday is superb.

Peter Dobbie in studio E with the newsroom pan opener really works.

Another question: when BBC News domestic and World simulcast each other (such as during the Paris attacks), is the TOTH countdown also identical across both channels with the only difference being the superimposed box?

The countdowns are not identical.

During overnight, the BBC News runs the simulcasts, and waits for World to cut into the NC feed before beginning the headlines. Thats why sometimes, World viewers see a milisecond of the end of the NC countdown as they opt in early.
