So many new F-4 Phantom decals - why?

[GVINCENT 5]

This may be slightly off topic, but when I was younger I saw many models of a Japanese F-4 Phantom in a light blue and white camo pattern with very soft edges.. almost cloud-like.  My searches for pictures of such have come up empty.  Anyone out there know what I'm referring to?  Maybe it was ficticious? I have seen many F-4 models painted that way back "then".. Just curious because I thought it was unusual and pretty cool in a way..

 

Thanks!
