I always thought he was blonde. I never interpreted it as him having actual blue hair as I did lenna having pink and faris having purple hair.
cecil starts out as a dark knight, and we never see him without that armor, cept when he becomes Paliden. when cecil becomes a Pali, its refered to as
"become a paliden"-he become girly looking and learned some W.magic.BIG WHOOP.
"paliden FORM"-assuming that is NOT what Cecil looks like without that armor.
honestly. do you think Paliden Cecil is what Dark Knight Cecil without the armor looks like? i dont.
