Nintendo in Japan, are allowing those ordering from the JP website, the ability to personalise their switch controllers through various colour combinations. No word as to whether this will be available outside of Japan, but given that we can imagine this would be hugely popular, it will only be a matter of time. Having said that, there still is delays in getting stock to many countries. I’d imagine most people right now would be happy with any colour of Switch, let a lone a personalised one.
