colors customarily used to designate whether a
baby is a
boy or a
girl. In ancient
times, the
color blue was considered a precaution against
evil spirits, since blue was the
color of the heavenly sky. Dressing a
baby boy in blue protected him from the
evil spirits who wanted to
cause him harm. Since girls were considered inferior, it was assumed that
evil spirits would not bother with them, and they were dressed in any
color. Much later, people became
conscious of the lack of a
special color for girls, and
pink became
standard for them.
