Maybe you should re-watch Madoka Magica given your new love of blue hair.
I'd also recommend new Winter 2017 anime Fuuka!
It's great we'll be getting another Nanoha/Fate movie. I hope they get a nice sendoff, given how the main continuity is clearly moving away from them (Vivid Strike had one flashback scene that had Nanoha and Fate's faces glowed out, lol).
