If the pinstripes were darker, the whole kit would pop. I assumed the Oppo logo being black meant they went lighter but I have had it mentioned to me that it was originally intended to be darker but didn't come out that way (I cannot verify the validity of that however).
Not sure if it is a Paladin issue but I find it quite puzzling that this kind of thing isn't picked up on before going into production.
From my (admittedly limited) exposure to garment manufacturing, you always get a sample to approve before going ahead. Surely they don't just go off the 3D mockup and hope for the best, right...?
