Usually brown, ranges from brown to hazel. There's a laser procedure you can get that costs $5000 USD and takes 20 some seconds to change brown eyes to blue eyes. Something with the cells of your eyes. xD
Oh! I've heard of that, once it's safer (heard it was still a bit risky, but that may not be up to date either) and a bit cheaper, I MAY consider it. Saw an after picture and the result is quite nice, actually ^^
