Teal Questions

The part time is a new bag style that is coming out so no it doesn't. You can try ebay to find teal as it's an older color. As for blue india, I'm not really sure because I haven't seen the color yet, but I think it's different than teal.
 
Yup ... the Teal is from the 2005 Spring season, so you would only be able to find it on eBay (or a consignment shop ... if VERY lucky).

You might want to take a look at the URL below, which identifies the Colors by Year & Season: http://ateliernaff.blogspot.com/2005/11/balenciaga-color-swatches-by-season.html

The Blue-India (Blue-Grey) is part of the 2006 Fall/Winter season; the bags won't be available until August/September (at least that's what I was told). It's tough to say exactly what the color will look like. Some of the pictures that I have seen (most from French fashion magazines) have made this color look more Turquiose whereas others look more like the Teal. I guess we won't really know until the bag is available!
