Nintendo allows you to order custom colour combinations in Joy-Cons
Nintendo has invested heavily in colour and peripherals for the Nintendo Switch, offering many different suggestions and now allowing custom combinations to be ordered.
Specifically, in the Japanese market, Nintendo allows its customers to choose the colour they want to have both every Joy-Con controller and the relevant straps on the purchase package. At this stage there are ten colour options for Joy-Cons and seven colour options for straps.
There is currently no such option in markets outside of Japan and no one knows if it will ever be given.
