Patching the font colours are probably a few lines of diff, adding a QR code to a text-mode display... way more complicated.
That's sort of what they're doing. It's just a two-bit QR code: Red, and Not Red.
So, one bit ;)
Hah! Yes, totally. Haha I wonder why I said that?
There is also a "not decided yet" state. Hence, you were right, it needs two bits. :)
