Well I got the color scheme sorted out so I edited my earlier post; here is what I found that is applicable to Swiss, Czech, and Hungarian Gripens.
According to a letter I have from Saab Aerosystems, the colors for the Gripen are custom but correspond to the following colors in FED-STD-595.
- Upper Surfaces: FS36173
- Lower Surfaces: FS36375
- False Canopy (Hungarian): FS36076
The markings are also done in these colors. Markings are as follows:
- Markings on the upper surfaces (over FS36173 base color) are FS36076.
- The Emergency Opening, Emergency Engine Shut Down, Fire Fighting, and Cut Here markings are FS36076 over a field of FS36375
- Markings on the lower surfaces (over FS36375 base color) are FS36173
Attached is a graphic showing the various markings based on a scan of a decal set. The writing is too small to make out in many cases so I've duplicated the wording and stated the location of the markings.
