One tries to be supportive of DC and then they go and pull stuff like this. What you see below is an early preview of Batwing #7 which features the character's first visit to Gotham. Batman and his closest associates share the cover with the titular; but as you may clearly notice, Barbara is shown with blond hair and purple accents in her armor to make her look like Stephanie Brown. I am not an avid fan of Steph's or anyting like that, but I completely understand why her followers would be p****d off to see how their feelings for the character are being played with in such a cheap way.
Saying it was a coloring error won't do it, as DC pays people called "editors" who are supposed to notice and correct this kind of things. What is the purpose of this, I wonder? Creating buzz and controversy? Test the waters for a possible second Batgirl in current continuity? Was it really an error, an oversight by potentially dozens of people? I just don't see a reasonable excuse for such a move. Now fans of Steph have to add this insult to their injury; so as a Babs fan I apologize to you and ask you don't hate on Barbara because of things like this; it's not worth it.
