Greg, KLM is smart enough to not WANT a complete makeover. It means you have to rebuild your entire corporate image and costs a load of money better spent on other things.
Several large corporations here did it over the last decade, they each spent billions on the change itself and probably lost at least as much again on lost sales as people didn't combine the new identity with the old products and went to other brands they DID recognise.
I don't like this change either, IMO there should have been no change at all. But as I said it's in line with the way KLM works.
The last change of livery involved changing the tone of the upper body blue by a few percent. The one before that changed the colours in the tail logo to a single colour (from a two tone blue).
They're an old airline, their livery a classic. The recognition it brings instantly all over the world is priceless.
Even if they do plan on going for something completely different, the change will have to be slow and gradual over a period of many years in order to avoid loosing that. Say they want to go all white (heavens forbid), then this is a logical first step. Next might be to drop the light blue upper fuselage (or more likely make it very faint) in 5-10 years time, leaving only the blue cheatline. Let's just hope that isn't the plan...
Orange doesn't fit in the KLM livery. Orange and blue clash together, and besides orange is the halmark of Air Holland who are hated by KLM enough that they'd do anything to destroy them (and have).
I wish I were flying
