Welcome to the forum Winston,
While I agree with your comment regarding Ferdinands/Elefants not being present in Normandy I'm puzzled how that means the standard mid war paint scheme is incorrect.
Quite often we hear the term "Normandy paint scheme" but all that really means is the standard mid war German paint scheme that was applied between Feb 1943 to Aug 1944 to all German AFVs. This consisted of Dunkelgelb being applied at the factories and RAL 8017 (Schokoladenbraun) and RAL 6003 (Olivgrun) being supplied to the maintenance units for application to suit conditions. The green and brown were supplied in paste form and were thinned with a solvent. This resulted in considerable variations in the density and hue of these colors.
The vehicle depicted is an Elefant which is essentially a refurbished Ferdinand. It has had Zimmerit added to the lower portions of the hull which means it would have had a fresh coat of Dunkelgelb applied. As noted above the green and brown would have been applied in the field after it arrived at it's next assignment (Italy?). I don't see any problem with the paint scheme.
