Change of user interface color

How can I change the interface color (from darker to lighter) in Mocha Pro 2.6? There used to be an option in the File/System menu! Please!

For recent versions we removed the option. We may reintroduce it in a later version.

Hi :slight_smile:
You can change the canvas color under mocha>view>canvas color…
Is that what you mean or are you trying to reskin the entire interface as a lighter tone?

Thank you , but I am interested in changing the entire interface, as it used to be in Mocha V1.0
