Hi Vengir! Thank for the feedback. You can try using  which allows us to pick CSS class for infobox per article. This way you can style your infoboxes as you like (within defined styles).

Here you can find more information about theme-source: Help:PortableInfoboxes

The current limitation is I will not allow you to build it form two variables "tło nagłówka" and "kolor nagłówka". Unfortunately your case is very uncommon and it is unlikely we will introduce such detailed, per-article styling. However, If you would need any help with migrating your current infoboxes to the new standard please let me know. Our whole team is located in Poland and we will gladly help :)
