You could argue that it was because the drivers were made by the Megahex so it can do that, but since the belt was scanned of memories they could just have yellow belts.

Well, the faceplate only changed when Takatora picked the fruit Mai sent to them, rather than when he put it on. So I figured it was also part of Mai's last ditch attempt to help them. She used her power to 'upgrade' the driver from mass produced Kurokage into a Zangetsu driver.
