i have an indian friend who also, obviously has very dark brown eyes and black hair (im white and have the same eye and hair colour, plus i have darker, olive skin compared t most of people) and she has green contacts, and i have to admit they look really really good!
if you want to see what colour suits you best you can go to www.freshlookcontacts.com and try lots of different colours on online by uploading a picture of yourself, and then you can see for yourself which colour you like best. when u get on the site, just click the 'fresh look color studio' button , its blue at the top and follow the instructions! but i really do think green would look really good since it looks nice with darker skin and hair, and surely more natural than if u had got blue contacts for example!
i hope i helped!
