I think big eyes should stay black and white (usually). I find it weird for shoujo to be anime. For me, it depends on the studio that adapts the manga into an anime... some do it better than others.
But if I really had to pick one, then Koizora because it has a lot of similarities with Bokura ga Ita in the aspects of drama, and I think Bokura was pretty successful. Well, I liked it.

You are like the dense main character in a shoujo manga.

And you will murder someone one day, pika. If you're my daughter.
