In the 70's, the Swedish Air Force wanting to create a new camouflage pattern for the Viggen, hired artists to render the Swedish landscape using geometric shapes and four colors (black, dark green, light green and tan), and with all angles being obtuse (>90˚) as much as possible. They came up with this pattern called the "FOA-kamouflage" (nicknamed "forests and meadows" ).

The pattern was applied from the factory. It was strictly regulated and looked exactly identical on each aircraft. If there was a repaint needing to be done, the pattern was applied precisely, using masking templates and tape measures. The colors however faded very quickly, the light green often turning almost yellow-green, and the black turning into a dark bluish-brown color.

I am really curious how I will succeed on these kits: I tried it once when I was like 18 and TBH, it looked like crap.

I did a Viggen 1/48 about 30 years ago, painted with a brush and enamels... didn't look bad as I remember it... of course no measurement whatsoever used with camo, it was free art 😄
