Browsing through a TOI article on indiatimes.com, I came across this article.
The aricle is about a girl who loses her confidence, a belief in herself 'coz she is dark.
This is a very nice written article, just go through it.
I think what matters most is not the color but the attitude!!
Yes, surely, the color is the eyecatcher and can be noticed in first shot, but after that its really how u carry urself is what counts.
