I like both the old Freightliner and Powerhaul colours. Not sure what the "new" one is other than the slightly naff logo in the OP, as the link posted further down is 404-ing.
Did see a couple of FL 66s passing Heaton Lodge junction light-engine on Monday, both in old green (not powerhaul) but one of them had the Freightliner branding in a different style with less-bold lettering (having now seen the image below to compare, I'm pretty sure it was Powerhaul lettering on the standard FL livery). Couldn't see the numbers from my seat in the 185 as I was too far away.
Also based on the image below, that orange livery is putrid! Both Powerhaul and standard green look far more classy in my opinion.
