What do you imagine Open Source means?

None of the inventors or well-known stewards of Open Source ideas share your belief.

Open source licenses are licenses that comply with the Open Source Definition — in brief, they allow software to be freely used, modified, and shared.

Unnecessary restrictions on use such as changing the colour of the gui, is not within the general goals of Open source software.

You can free to change the color of the GUI in the code and build it yourself. Change the values here to your liking - https://github.com/SimpleMobileTools/Simple-Commons/blob/mas... .
