obakesan, May 18, 2018 : hey, I was lucky to try them at launch. mirror black is like a mirror, you can see your reflection in it. pretty slippery and can get fingerprints on it. midnight black is like normally aluminum midnight black, it's hard to believe it's glass, seriously, its amazing. it's matte like on 5/5t. The white, aside having the pearl sheen and rose gold trim, felt like midnight black to me, reminded a bit of the old white oneplus. pretty nice. hope that helps.
