Yes the orange is a bit of a "signature" colour. They have done this colour on the Passat Alltrack and Beetle also. It works well at car shows
And yes I think all the non-greyscale colours will date. It's the kind of thing that will be only be available for a short time so if you do like the colour you'll have to purchase it while it's available.
The Caribbean blue is a bit of a funny colour too. It may look OK in the flesh - brochure colours are really hard to pick.
