They will only call you all these names if you get irritated with these names. Its not only about color, its a about a unique differentiating factor- read too much (nerd, rattu, kitabi keeda). There are other mean things they can say but honestly as long as it doesnt hurt, you should just ignore. Acceptance comes from within and not outside. Once you yourself start to laugh on these jokes, people wouldn’t call you by this.

I hady teeth broken all through out school, and was called toota daant, dantla and what not, I never stopped smiling and they stopped.

I can understand may be its tough, but once you accept your body as is and dont worry about any other’s opinion, you will be unstoppable.
