Is there a difference between the male and female versions of these dolls?

Opacity? or are there new colours? :O I'm not familiar with the whole collection of either so I'm not sure if the male set has new colours.

Pretty sure the difference is colors. The male versions have several colors which are much different than the female. Male have red, purple, orange (female has orange but it has tints of green on it, male is all orange)

I could be wrong though on some part.
