I have a black one and a blue one - the black one sits in the cupboard - the blue one travels with me.
This case accents the phones well - and grippy/comfy too -
No regrets with my Blue Pixel paired with a UAG clear case. Best case I have owned as far as I am concerned. As for choice of color, I wanted to do something different plus being from Chicago and the Cubs winning the World Series last year I thought it was a nice tribute to them
Regular Pixel owner here, but I love the blue! Have a Spigen ultra clear case on it and like that as well. My previous three phones have been all black, and the white/blue is a nice change.
I love the Really Blue. I agree with poster above. It is more beautiful in person. Plus, there are just too many phones that are black, silver. Thankfully, Google did not make a "rose gold" either!
