It seems to me it's very similar painting - 10th pzdiv vehicles have traces of dried mud and dust on the armor, while 4th pzdiv diesel oil stains
The top 5 vehicles are the 4th division and the lower ones are the 10th
Just to be clear - in fact, up until 1943 and the Kursk battle (with minor exceptions) painting of German vehicles in Europe were simply the different shades of the same color "dunkelblau".
Only in the years 1943 to 1945 will occur an explosion of German art of camouflage
Let's say the similarity is intentional...
Incidentally, to make camouflage something different, for example during the French campaign, I also used camouflage with green-brown spots on standard vehicle painting, while these camouflages are highly debatable and some specialists believe that there is no evidence that they were used before 1942 (eg. Jean Restayn). Others on the other hand, they believe that it was a regular camouflage of armored units since 1937... Honestly, wait for the battle at Kursk, then camouflages will be much more interesting
