Italics or Blue?

Hello lovely people!

Just looking for some advice regarding how to present bilingual posts – after some experimenting I’ve come to the decision that alternating chunks of text is the best (the page jumps didn’t work for e-mail followers). I now got two formats that I tried and I’d like some opinions which one is easier to follow?

The first method I used was to differentiate the second language by putting the paragraphs in italics like in this post:

Rest in Peace? The Wandering Remains of Christopher Columbus

But because my theme puts quotes in italics and I sometimes use italics in a text anyway, I thought that maybe putting the second language in a different colour might be better. Like this post:

The Siege (El asedio)

In which format is it easier to follow the text for a monolingual reader?

Thanks a lot in advance!
