I think it's almost the same as the difference between which and what. When using qué, you say: Que es eso? because there is no range for you to choose from just as you will say what's this? not Which is this? The object "eso" is pointing at is quite clear already. When using Cuál, you've got a range. As your example goes, Cual es tu color favorito? 'cause there're only several colors in the world, thus there is a hiding range behind the sentence which we usually omit as "Among all the colors, which one is your favorite? " Therefore we usually use Cual here. That's my own understanding. Hope it will help you/

中国繁体字改成简体字是在1949年吧，不过港台地区用的还是繁体。因为简体字是根据繁体字改的，所以我们可以由上下文和字的大致形状判断出这个繁体字简化过来是什么。像我的话因为比较喜欢阅读中国古典文学，所以常用的繁体字基本都认识，也能够写。平时读古书自然会积累起来，而且很多部首和字符都有固定的简化后的形状，能够帮助辨识。

Those characters were surely all impressing.
Yet to me, Natasha in War and Peace stood at the top.
