I have to say I'm in two minds about the new SAS livery. It seems perverse to paint only part of the engine nacelles red, and the titles on the fuselage are virtually invisible under most lighting conditions. The blue tail stands out well though (as it does on the new Delta colourscheme).
SAS have a very good website at www.sasflightops.com and this also features the new colours. (Sorry I don't know how to create a link).
Finally, B737s have been known (at least to British spotters) as 'pigs' for a long time, probably going back to -100 series days when they had short fat fuselages.
