Might be similar to this one that's operating in Yorkshire
That's only of the Class 144 refurbished prototype. Nothing has been said about the new livery - if there will be one at this stage.
I personally doubt it would be the same as 144012; the colour scheme on it (purple and blue) seems the same as the current Serco/Abellio joint venture.
