Yes i know RAF color is CG, but i dont skip RAF color, and 37200 was the closest match. I seen other group photo and IMHO the Austrian Typhoon color is not same than Luftwaffe color. Rather greyis than bluish.
If i build and paint a spanish Typhoon i would use 36231, for Italian 36251 (Close match and can buy this color), 35237 German, Cam, Grey for RAF and maybe 36270? for Austrian.
Your paint chart is a good match for that photo. The German colour is correct (I know it's 35237 for certain) and the Italian colour ties-in with what most of us already suspect. The RAF colour
