Change Color in a text out node

Hello, everyone,
Since my English is unfortunately not so good anymore, I prefer to use Google Translator to formulate my question here.
I'm looking for a simple way to change either the background color or the font color in a text out node. I don't want to do this in general, but only with isolated text out nodes.
Is there a way to do this and if so, where do I have to enter it exactly, since I'm still relatively new to Node Red and I'm sure I still have a lot to learn.
It would be great if you could help me here.

Best Regards
