This is somewhat difficult as playing what if games are indeed hard to actually determine as what would be right or wrong, or in this case, better or not...

However, I find myself not wanting to swap Cloud's blonde colour for that of Zack's grey for a number of reasons. Cloud's eyes seem to stand out more when he has the contrast of the blonde to compliment them. I am a person that loves people's eyes, as they hold so much emotion, and find, personally, that eyes almost seem like they are the pools of a persons thoughts, emotions, in essence, their soul. Having Cloud's eyes stand out that much more demands attention, for one to look into them - I like that.

Another reasons I prefer Cloud's hair to be blonde is that it is a stark contrast to all of the other heroes, except for that of Cid's And really, blonde haired individuals have been attributed to being angelic, and although such a trait may be overused, I still prefer it, especially when Cloud can many times seem cold and uncertain.

My final reason would be because, well, it's what I grew up, it's always been what I have attributed to being Cloud. It's difficult to shake that from my mind, so in many ways, I am biased.
