I plan to generate QR code in the form of arts, like this http://investorshub.advfn.com/QR-Bar-CODE-24659/ . But the common barcode reader can not read it because of the color combination. So I wonder how to solve this problem.
Wow, I did not know QR code barcode can be created in such a creative way. But there are existed standards for the color combinations of created QR code. So I think you would focus on how to create QR code with acceptable color combinations, instead of developing the QR code scanners.
Here I attach an image for you, which is about the barcode color combination. Good luck.
