New QR Code App in the additive RGB color system for higher accumulated information density

Abstract

The decision to use Google Colab for this project is based on the need to make the technology accessible to a wider audience (especially traditional graphic designers – old-school pencil and paper artists –, freelancers and diverse makers and/or budding AI coders), including all those with no prior programming experience. In this work, a detailed tutorial is presented on how to use Google Colab to run Python scripts without the need for local installations, with a focus on generating and decoding composite QR codes (QRGB) from information encoded in three color layers (red, green and blue). The process of adapting a script originally designed for Visual Studio Code is explained, highlighting the advantages of cloud computing for democratising access to advanced tools. Through this approach, we seek to foster digital inclusion and allow more people, regardless of their technical level, to explore new possibilities in the use of open source for creativity and innovation and to offer. This application is offered as an open source project and is available for free so that designers, freelancers, makers and any user interested in marketing or advertising can use it and share it with their potential clients, thus expanding its reach and applicability in different creative and commercial fields.
