Plus, those imageson Twitter/X above are dreadful with so much interference and Moire effect, something which is difficult to hide in most broadcasts, never mind which angle is used.

Well they aren't going to be perfect, they're taken on a phone at a funny angle... I was talking more about the colours and washed out effect being less taken on other cameras - somewhere between lighting and racking there will be a fix - but I don't think it's a simple case of the lights bleeding onto the screens washing them out - I think it's a blend of two issues, the flesh tones don't look right either even in the more shadowed areas of the set.

It may be the tungsten lights they're still using too - they have a blend of tungsten and LED and some appear to be angled towards the set rather than the talent in front of the set - obviously the lights do get moved for the Politics Midlands filming, I sometimes feel like they forget to put them back. It doesn't look great though, you are right there but they've always had lighting problems for some reason...

In 2012 when they got their first new set after moving to the Mailbox, it started the day looking fairly decently lit:

and by 1830 it looked like this:

Have you considered emailing them and pointing it out to them if it bothers you that much?
