As GAZ has mentioned, just looks a different colour in the pictures because they're taken in strong sunlight. Really no reason to think its anything other then Odyssey.
Missing Link.. Petrol Blue was only available on 182's and v6 255's. It was previously called Paddock Green, but never heard of it being used on anything.. as odd as that sounds. Although its possible it may have been used on the Avantime. The Megane coupe sport had the colour option similar to Petrol Blue/Paddock Green, but not 100% it was the same colour.. damned close if it isnt though!.
Silent-scone... silence..
These i.d. illusion paints vary in colour enormously depending on light conditions. Has anyone ACTUALLY seen this car for real? Colours also vary from the camera used wouldnt you agree.?
