Nope. Black people were totally offended by that. The difference was that must people didn't care.

They're all color coded. Black dude is black ranger, asian is yellow ranger, nerd (logic) is blue ranger, white girl is pink ranger (girls like pink), jock (agression, also possible native american ancestry?) is red ranger, hippie is green ranger who becomes white ranger and he's a white guy
