Just to finish this and get back on topic ! The paint code on the 500 in the picture was 203 which Fiat Dealer says doesn't have a name ! If you order "Fiat Volare Blue" from a paint supplier what arrives is Fiat code 952 which is a much more grey shade. That colour isn't wrong though as a Google of Fiat Volare Blue shows cars in both colours. At that point I gave up as I have a can of Ford Olympic Blue here already and that is the same shade of blue as the Fiat in the picture !
Nope.
Fiat have only had two different light blues and they are Cha Cha Cha Azure Blue and Volare Blue. The photos on google images just look different because of different light and different cameras.
203 is a different colour and is metallic for a start.
