I confess I find the Golden Flash gold colour unattractive.
Yes me too, my Gold flash is Gold of a more modern vehicle, ( Susuki I think, would have to check with the shop that got me the paint), it's a mixed colour they got for me (very reasonable price).
It looks good, not to garish but more to today's taste then 50/60 s.
Purist will pull their hair out but I think it's quite allright to go for what BSA would be using if they were still producing bikes, it's your bike make of it whatever pleases you.
