I don't know how QR codes work exactly, that will be my homework for tomorrow, but I'd imagine it would be possible to add data to their codes by introducing colors.

I could be totally wrong, but if the corner squares are meant to callibrate the dimensions of the qr itself, then having base/primary colors that the phone could callibrate to in order to pull additional data based on the hex codes of the colors would potentially open the door to 1mil x more data storage.

Tomorrow, I will discover my presuppilositions are totally wrong and this theory will be trashed.

Good night ✌️🧡

QR codes are like barcodes, where instead of various black and white bars, there is a grid of little white or black squares.

The three corners are used to determine the edges of the QR box and define the grid area so the color of each little square can be read.

A color based barcode would be difficult to implement because colors are not always reproducible, but a contrasting light and dark pair can.
