Black and white go with everything which is why I am a fan of monochrome sets, if done right.
Kuro/shiro is one of my favorite sets because of the Japanese modifiers. Sure, sub legends are cool and all but when backspace becomes 後退, that is a whole new level. Aside from the amazing mods, I got a RAMA PVD brass keycap with 黒 written on top; yes, I know it is just a keycap that says black but I love the look of kanji. Aside from the cool aesthetics, I again am impressed with the feel of PBT over ABS although I am annoyed that some of my spacebars are wrapped.
