Joomla 4.2.9 SPPB Pro 4.0.10

I have a section on a church website home page with 6 news items pulled from Joomla articles in 3 columns. Everything's fine except that the text colour differs for 4 items and I can't figure out how I set it up originally to be able to fix it. Basically because the module set is on a blue background, I need the description text to be white which it is for 2 of the articles.

I've checked the row setting, and module setting in SPPB and selected for white text - if I change the text colour in the row setting, it works but just for those 2 articles while the text for the other 4 is black. I can see in F12 where it is in the coding - I just can't figure out where it is to change it (if that makes sense?). I can't obviously change the text in the article to white so am stuck as to what I'm missing.

Site is here https://www.bloomfieldmethodist.org.uk/index.php and it's the Latest News section 1/2 way down the page.
