2d barcodes are used for cradle-to-grave inventory tracking by systems like Glovia and SAP. everything from transmission gears to soda pop are tagged during manufacture with numerous 2d barcodes that change at different stations, and at different times.
it doesnt matter what your new standard claims to achieve, it is useless without industry adoption. Toyota, Honda, Yamaha, Ford, Dell, and countless other manufacturing titans have invested collective billions into the QR implementations of their factories and arent going to re-tool just because your standard has colors.
QR is also massively resilient to failure. Try this experiment: cut a QR code in half, try to read it. It will succeed. This resilience is pivotal in harsh environments and especially during international/trans oceanic shipping.
black and white QR can be engraved on shipping containers and is resistant to corrosion, solvents, and the environment around it. QR codes are regularly burned at thousands of degrees as part of the heat treatment process for hardened steel, and still perform. Vision systems for forklifts and robotic cranes at shipping yards (most are robotic yards these days) rely on near/far vision systems developed by Intermec and other companies to read a code the size of a postage stamp from up to 150 meters away.
