Hi all, hi Misos
However I still think it has two grey camo - see difference between lighter and darker color on the rudder (just above left peak of the star), on the upper fuselage between digit 9 and rudder and on the left horizontal stabilizer between trimmer and right hinge - basically all are there where one could expect them according to the NKAP AMT11+AMT12 scheme.
Plane is just cleaned and polished so difference between two greys is not so evident on this overexposed photo taken during sunny day from this particular direction.
The number 69 is smaller than factory painted numbers, so the plane has to have been repainted over the camouflaged base. Contrast between fresh camo colors should be strong, so I think that was repainted in uniform grey, and some traces of the previous camo are unperfectly covered by the new paint.
Regards
Massimo
