Tea garden? Tea garden? Clearly retirement is different for your goodself; I’ve just got back from the Gym where I nearly killed myself(!)
The best colour I’ve found to represent the Bundeswehr’s Gelboliv (“Yellow-Olive”) is Tamiya XF-51 Khaki Drab - obviously for those vehicles up until 1984 when the 3 colour scheme started to come in (without teaching you to suck eggs I’m sure, just remember that it takes years for an Army’s vehicle fleet to be completely re-painted).
Revell, not surprisingly given their German predilictions, also do a “Gelboliv” but whilst it’s a match for the real paint, I feel it’s too dark for 1:35, though I have used it until I discovered the Tamiya paint.
All subjective as always with colours, but for me, Tamiya XF-51 is the way to go. That Spaepanzer will look just fine in it I reckon!
