The main frame of the Brompton gets the most attention while Kick stands and roller racks are unsightly but they serve a good purpose. Therefore, using contrasting colours for the fork and rear triangle helps to divert the focus away from the kick stand and roller rack. Choosing a black roller rack and kick stand is the best choice making it rather unnoticeable. In my opinion, going contrasting colours for the easy wheels even makes the roller rack “invisible” from a distance.
Colour Balancing, Playing with three colours or more.
Taking from the theory of colour balancing in the world of classic suiting. The colour of the pocket square can be of the same base colour as the socks, but never the same fabric,pattern/design or colour as the necktie.
