How can I customize the highlighting of my custom tags?

Question

Syntax highlighting

I can't find where I can add and customize the highlight color of my own tag. Which is not registered and, accordingly, is not in the standard ColorScheme:
well, for example for
<newtag> </newtag> или <<!-- --!>>

Answer 1

You can add custom tags here:
Settings > Editor > Inspections > HTML > Unknown HTML tag > Options > Custom HTML tags
As for highlighting:
Settings > Editor > Color scheme > HTML > tag
They will be highlighted in the same way as other tags. You cannot set a separate color for custom ones (as far as I know).
