That would make a great sequence question if it hasn't already been one, but I'm afraid it doesn't match the colours as well we you remember...

Sequence was
5 - green on yellow (SA), Thunderbird 5 was there space station but it was pretty much just silver and bronze
4 - black on white (ENG), Thunderbird 4 was yellow and... pink?
2 - Yellow on green - (AUS), Thunderbird 2 was yellow on green so fair enough
7 - White on Black (NZ), As far as I know there was never a Thunderbird 7.
As an aside, you may like to know Thunderbirds is being remade and, while the obvious initial reaction is abject horror, the ships actually do look quite like the original models although Thunderbird 2 isn't quite as rounded.
Yours, someone whose childhood was dominated by Thunderbirds dinky toys and who desperately wishes he'd kept some of them
