What's the reason why "Shokugeki no Souma" has so many color chapters recently? Does anyone know why all the latest releases (about 5 chapters) of Shokugeki no Souma have all been in color? It's great and all, but it's starting to scare me.

For some reason, it's hard to find copies online, but I read manga on my phone and all the latest chapters are like HD full-on color.
The manga is normally published in the Shonen Jump magazine in black and white format, like the others, but the magazine has a new website called Shonen Jump+ where you can buy the official color chapter to view online.

Only One Piece and Naruto eventually also have chapters in color on the web, and it's because Shokugeki no Souma is quite popular and as an extra for the final arc autumn election.
