This is what’s great about these studios they can do fantastic things with lighting, unfortunately Studio E has the real news backdrop so despite the ability to change the lighting it’s limited due to it which unfortunately means BBC News Channel always has the red white colour theme, this is why I watch BBC World News where the colour lighting is done by programme.
