Colored Contacts for Dark Eyes

Hi. Im thinking about getting colored contacts. Im asian and I have dark brown eyes. The eyedoctor gave me 4 colors (variations of light blue and green). I dont like any of them because they didnt change my eye color at all. I was wondering if anyone could give me some info on somewhere else I could order contacts or try colors. I want something more noticable and colorful than my traditional brown, but not anything too dramatic. I also heard about circle lenses, but Im not sure if they are safe & available in the US?

Anyway, my picture is to the left and any feedback would be great.
