There exists a dark blonde hair color. Such as a dark ash blonde. There are some people with true dark blonde hair, but for the most part the dark blonde line is for people who don`t want to admit they truely have brown hair. What really pisses me off are the bleach blondes with dark brown eyes. It looks so obvious because we all pretty much know that a true blonde isn`t going to have brown, especially not dark brown, eyes.  That would be like two clear blue eyed parents having a brown eyed son. It doesn`t work like this because blue doesn`t carry any brown genes, so if two blue eyed parents have a son with anything other than blue eyes, I`d be wanting a DNA test. The same isn`t true for two brown eyed parents having a blue eyed child, however. Brown eyes can carry blue genes. Of course everyone probably already know this, so why do I even bother? :p I know more than 1 guy who has blonde hair and brown eyes. It's not common, but it does exist.
