How to change the colours in v 8.2

Hi Team, does someone know how to change the colours / create a new theme in SuiteCRM 8? I had an instance running in version 7.x where i created my own theme sucessfully via the following guide, but this is not applicable to v8.x.

I already found the folder /public/legacy where the themes are stored, but i am having issues with compiling my new theme that i created within the themes/suite8/css/name of my new theme.

That would only work for legacy modules, not for all the other modules in v8 (most of them).

I don’t think there is currently any documented way of achieving this.
