Spray paint

The colour of my 2014 Kingham is Golden White. Code Fiat 503. The problem is when I buy a spray can mixed to this code it doesn't match the original by a long way. It is almost silver. Has anybody else had the same problem?

I have just posted this on another post, this is the only way to match up paint , they will be able to even make spray cans for you

Do you have any industrial estates near you, there is normally a paint supplier to the car repair trade that will be able to mix this for you, as the van is of quite an age I would suggest phoning around paint suppliers and see if they have a paint spectrometer and get a perfect match mixed up to the sun faded paint
