No, orange is the complementary colour of blue, which is what the oceans are in that logo. Perhaps a little less politics and a little more graphic design is in order, if graphic design is what you want to critique.

It’s a silhouette. An OUTLINE. The person depicted in that avatar is no more white than they are standing in front of clear, blue skies: it’s an abstract colour scheme. There is no race involved, much like there is no eye colour or age involved. I guess the only thing you can viably complain about is the fact that the outline is slim (“Where is the representation of overweight people? Rah rah!”).

But overlaying avatars w/a map of the world forces you to add a third color, at least if you want the avatars to be remotely clear/discernible. So what color do you use?

I personally might have gone for yellow — I’m sure it was tried out — but orange is stronger, less lemony and springtimey and feminine (and, I guess also less open to interpretation as “Asian”). Pure red would be too USA/angry. I suppose green would have been another option, but if you want a warm contrast instead of a cool compliment to your blue and white then orange is where you end up.

And, uh, females DEFINITELY can’t hair haircuts like that. Because I’m not female with a haircut like that at all.

No, I think the problem is that the default icon is not heteronormative enough. Girls can’t choose girly, long haired icons! GOSH!
