It was harder to read yes, the other thing I noticed was that LOROL haven't updated the list of cards that are accepted above the chip and pin device, despite the machine accepting my debit card which Southern never accepted. (Cue embarrassing dash to the cashpoint!) Although they have on the touch screen in the top right hand corner 'All major credit and debit cards accepted' But you have to look carefully as the text is tiny against the colour.
Sorry to be pedantic, but the colour scheme is only used at London Overground stations, not LU, which has a much easier touch screen device, which I'd like to be seen implemented when the old Southern machines are replaced next year.
