1. Go to the avatar creator (either to make a new avatar or edit one... it doesn't matter)
2. In the list of things to edit, click on "My Features"
3. Once in my features, leave the hair changer HIGHLIGHTED but don't actually click it
4. Now you wait (Don't move anything) for about 40 seconds and watch the "hair changer" icon very carefully... when it spins around, click it very quickly as it spins for only a brief second
5. If done correctly, you should have an additional page of hair colours (i.e VERY light green, light blue, etc)
This is nice if you're after a Japanese anime effect for your avatar
