I'm developing a QR Code generator and would like to understand if it is okay to have a different color combination for the QRC image other than the black and white?
Will it cause any difference in the amount of data that can be stored or in the error correction levels?

But does a QR code must be black and white? Of course not. QR code can be either colorful or recognizable only if it can be detected in binarization. Colorful QR code can not only leave people a deeper impression, but it can also convey more information than standard QR code.
Although most QR Codes are black and white, they don't have to be. A QR Code can be any colour and can even include more than 2 different colours.
QR Code is standardized as shown in the table. It was approved as an international standard in June 2000. This shows that QR Code has been accepted internationally, ensuring its widespread acceptance not only in Japan, but also internationally .
Despite commonly appearing in black and white, QR codes can actually be printed in a variety of colors — which can be a great way to make them match your brand better. However, there are some things to consider when deciding what colors to use.
No hard and fast rules - you can have a QR code in other colours, provided the contrast between dark and light is sufficient to be interpreted. No difference in the amount of data that can be stored or any error correction possibility, just in the ability to separate dark from light in order to decode.
