Likely Yes, but you need to define your custom style:
by grepping through PTK source I can find the following:


Then you define a Pygments Theme and it should "just work".

We need to write documentation about each of these, if you figure out

Do you want to open issue for each of these, we can try to improve

Yes this has been reported, we missed that because of the weird

Thanks for your feedback.
