Custom theme


I’ve been searching how to deal with themes but it’s still a kind of mystery.
I don’t know if I have to create a subtheme of SuiteP or if I can create my own theme.

Ideally I’d like to be able to duplicate SuiteP and create my own theme.
I followed some youtube videos like this one :

but the guy doesn’t seem to know what he’s doing.

However I followed what he said and I was able to create and choose my theme.
But then I’m not able to make any change.
I don’t know where to change the colors and that stuff, it just doen’t apply.

Is there some documentation somewhere ?

I also tried subthemes, following this tutorial :

but it would make more sense to create a theme than a subtheme.

Any idea ?


I was able to figure it out.
I’m going to post here what I understood from theme customization, it can help other people.
