One should not be dogmatic about colors (the French were not). At least for M.S.406s, three different (approximate) coloring patterns exist, based on where the planes were built (the early models have a clear blue-gray area over the cockpit). No clear definitions for the colors used exist, but there some often quoted F.S.595b numbers:
| Color (French name) | FS 595 (with help from D.Veres) | Paints chosen for my M.S.406 | Paints chosen for my C.R.714 | |
|---|---|---|---|---|
| Dark blue-gray (gris bleu foncé) | 35164...35320 | Model Master "Intermediate Blue FS 35164" | Hataka HTK-CO82 "Gris Bleu Foncé" | |
| Khaki green (kaki) | 34087, 34097, 34098, 34102, 34127, 34151 | Model Master "Olive Drab FS 34087" | Hataka HTK-CO84 "Kaki Française" | |
| Dark brown (chocolate) | 30045, 30097 | mix of 50% black, 50% Testors "1166 Brown" | Hataka HTK-CO81 "Terre de Sienne" | |
| Light blue-gray (gris bleu clair) | 35320...35526 | Model Master "Medium Gray FS 35237" | Hataka HTK-CO83 "Gris Bleu Clair" |
The dark brown may appear somewhat dark, and if lighter colors look better then go for it (hence my choice of the Hataka paint for the Caudron, also supported by [2]). According to [1], the paints used by the French were not necessarily of very good quality, hence heavy weathering is implied.
