For those who haven't caught it, my plan all along with this build has been to do my own replica of the original box art model. I went with orange and black only because that was my own interpretation of the colors used on the original "model" on the old box art label. Also because I didn't want just another red/white/black version, to me it would have looked too much like the ARF.
The "photo" on the label is in black and white, and the only color used on the label I've been using for reference was orange. Since all the 'Streaks in the series were always shown/advertised with the black leading edges, I went with that. That's how I settled on the colors for my version.
I'm going into the shop in just a few minutes here to shoot what will hopefully be the last coat of clear.
