How Can I Overwrite the Basic Theme: Vanilla?

Right.

And what you doing on palettes is brilliant! Making clearer, as you are doing, how they work with CSS classes is gonna help everyone colour better!

My point was more generic to the OP.

Does “Vanilla” need to be overwritten? I dunno!

I personally think it is rather well written, though very difficult (because of it’s size) to get your head around just reading it’s code.

My point was simply whether a more interactive visual way of understanding it, that teaches you the classes interactively via screen demo could help?

Just a thought
