For all People interested in this Subject:
After doing some Research I found out, that the Scheme in Orange that AZmodel presented for the Version with photogrammetric Stripes on the sides wasn't orange in Original but rather greyish blue.
Imperial Japanese NAVAL Airforce (IJN) Experimental Planes were orange, later in the war the Top was camouflaged in dark green with only the undersides left in orange. Trainers had camouflaged uppers and yellow undersides, just like the british "trainer yellow" (the Japanese took a lot of inspiration from the British as can be seen by the yellow leading edges of the Wings, like the British had late in the war in Europe).
But as indicated by the "キ" (Ki) Number, rather than the Letter-Number-Letter-Number code of the IJN,
Ki-78 was an IJA Experimental Plane and hence was not orange.
Early Photos show it in natural metal, later it appeared darker in black and white Photographs but as the designer recalls, it was greyish blue and not orange. See this for reference: aviationofjapan.com/2014/12/some-observations-about-ki-78.html
So Platz have corrected this while I just found out AFTER I painted my AZmodel Ki-78 in orange...

The fact Kora Models already made different Decals for the Kit prior to it's release gave me hope. I am so eager to get an example of this Model so I contacted Special Hobby to ask when it might be released. This is what they said:
this is a project we're working on and we hope to release it this fall. As soon as we have any news or pictures to share, they will be published on our blog and Facebook site.
Have a nice day"
So we will have to wait about half a year longer from now.
