I feel your pain... I too bought a Turkish Green M6R (Titanium) for my wife - due to a distinct lack of choice and a very good limited-time offer - and ended up riding it more than her. However, IMO it was one of the worst colours and I do agree it looks kinda feminine. I would actually have preferred a Hot Pink over it.

Ultimately I switched the Ti parts over to another bike and sold it. Phew.

That said, it may be worth your while to put it up online at a small loss and start riding it normally. Give it about 6-12 months to accumulate the usual newbie Brompton-owner scratches while planning your perfect powder coating combination. You'll have a lot more choices to make your Brompton look unique and brand new.
