Planning a new blanket

It's been a while now since I finished my Northern Zealand Blanket that I crocheted using the Tunisian Full Stitch. Find the blog post and free pattern for that blanket here. 

I always like to take a little break after finishing a blanket before I start something new - just to get a little break and decide what I want to do next. We've also had a few very busy weeks lately - at the end of June we moved into our first very own house. So as you can imagine, we have been kept quite busy both during the week and on the weekends. But now I finally feel like I am ready to start another blanket - and so the whole process of determining colours, yarn and a pattern can begin :)

I have to admit, I'm a little bit confused. I'm torn between choosing colors that would complement our living room - or just choosing colors that I like, but that wouldn't necessarily blend in very well. The mint and brown color option way below would definitely work well in our living room - and I do love that color combo - but I am also drawn to number 2 and 3, in particular. With the colors of square number 2, I would like to do granny squares (not with granny clusters, but simple double crochet) - and possible arrange them like in my colorful squares blanket here).
