From memory, which isn't the best, the colour code should be inside bootlid or tailgate
most were painted in Max Meyer, there will be a base code with either a lighter or
darker shade. A good body shop will be able to match to the original.
I expect the "refrigerator" colour is Ford Diamond white an easy option if you can't
be bothered to check original colour.
there are a lot of good bodyshops around, depends on your location.
