Yes - I think it would be interesting to see them actually produced. Could we get to 60% white pixels? Or 75%? There could maybe be two solutions: * Darkest/B

Yes - I think it would be interesting to see them actually produced. Could we get to 60% white pixels? Or 75%? There could maybe be two solutions: * Darkest/Brightest allowed by the QR algorithm, * Darkest/Brightest technically valid, which would would not be chosen by the algorithm (i.e. if one manually chooses the masking pattern. Perhaps also more solutions - 'Darkest/Brightest recognized by software X/Y/Z'
