P.O.W.: Prisoners of War (pink variant)

P.O.W.: Prisoners of War is a side-scrolling beat-em-up developed by SNK Corporation and published by SNK Corporation of America in September 1989

This ad is a variant of an otherwise identical ad, but here the blue SNK logo and blue stripe in the stylized "S" logo are colored pink.  What does it all mean? Was this a prototype design that was changed for not being "macho" enough?  Is it not possible to ass-kick your way to freedom with your bare fists while wearing pink? Will we ever learn that no amount of grenades, knives, and M-16s will make us a man if we aren't man enough to feel like we're kenough without them??
