Hello, this is busa01.
A6M2 (A6M2b Model 21) painted by orange do not exist.
The prototype and trainer orange (color code C1 orange yellow) are not used for A6 series.
It was enacted that IJNAF painted orange to a prototype at the beginning of 1943.
Therefore, the prototype of A6M1-M5 was gray green.
Incidentally the prototype of J2M1 was gray green, and the prototype of J2M2 was orange.
And Ka-101 were gray green.
A6M2-K painted by orange is not used for the combat.
A6M2-K painted in an orange/green was used for the kamikaze attack.
Since I am a Japanese, I do not want to use the skin of a kamikaze attack in a game, although it is a personal opinion.
