If the information surrounding the colour scheme is based on the Guardian articled I originally quoted and linked to in the SWR thread, then I fear I need to nip some potential misinformation in the bud: There is no talk about a red, white and blue livery, merely that the train will carry the GBR logo, which is claimed to be red, white and blue.
To quote the article:
At the rarely experienced hour of 6.14am on Sunday, the first train to carry the Great British Railways branding will make its way out of London Waterloo to Shepperton: traversing the Surrey commuter belt emblazoned with a red, white and blue GBR logo, and proudly renationalised to boot.
The next train with the planned state body’s branding may be some years behind it. But the Labour government hopes to grab the moment to demonstrate to an increasingly impatient electorate that the wheels of change – in rail at least – are finally turning.
The first renationalisation, landing on the late May bank holiday weekend, is one of Britain’s biggest commuter services – although the trains, including the one currently getting the GBR paint job in a Bournemouth depot, will still run as South Western Railway for some time. As the first emblem of a potential new era pulls into the station, what does the shake-up mean for the rail industry – and will passengers notice the difference?

A subtle difference, perhaps, but the livery / branding could therefore be white, red, blue or a combination thereof, even purple, green, yellow or black (albeit highly unlikely). It may well contain red, blue and white, seeing TfW already does a red and white livery and Scotrail mostly blue. But who knows. Could even be an evolution of the Greater Anglia livery with a splash of blue thrown in or a throwback BR InterCity style livery for all we know.
I think the livery is most likely going to be quite minimalist and contain a lot of white or light grey, with only a splash of red and/or blue thrown in apart from the GBR logo itself. That is the "modern" or "hip" thing to do, even if it does mean trains could get dirty a lot more quickly. Shame if it means great liveries such as GWR will get retired...
