I was led to develop, for the 4D Go mobile project editor, a management of colors and their conversions from one system to another, the calculation of color harmonies and even the detection of the dominant color of an image. This project is the result of this research in the form of 2 classes: color & bmp and a test form.
I strongly encourage you to enrich this project through pull request. This can only benefit the 4D developer community.
Enjoy the 4th dimension
