Problem with customizing blog title color

Hello everyone, I’m new here and to blogging in general, and I’ve just ported to wordpress a blog that I had started on blogger some months ago. I’ve got one last problem with it though and since I hear on this board you’re pretty helpful, I’d like to take a wee advantage of you. ??

The problem is that the blog title, which previously I had customised to be white, started at some point (I thought it was after I had installed a plugin, but deactivating it didn’t change anything) being red, and returning white only when you hover on it. I’ve already tried to locate where in the css I could change this with firebug, but with no success; I tried a couple of plugins but they didn’t seem to detect any “red” settings in my css; and I checked but I didn’t see any recent thread here about this matter. Basically, what I’d like for it is to be white all the time; if necessary, even disabling it being a link (I guess in that case I could just set a “Home” button on the header).

My blog is this: https://studiodalvero.com/ – and, as you’ll see, it currently uses the Church theme (which I hear it’s technically a child theme of Omega). Can anyone help me please?
