Compliment?

So today I went bowling with some friends who were in town for the holidays, and this girl who also had a Mohawk caught my eye. I noticed her staring because she was only a few steps away so I complimented her on her Mohawk because it was a cool color turquoise and she just gave me the cold shoulder and walked away. I am certain she heard me which makes me wonder either how I went wrong or why she didn't have the decency to say thank you or even a smile. I don't know maybe I am just overthinking it but it got to me I suppose I am just venting because I am used to punks and Mohawk rockers being generally friendly toward one another. Thanks for making it this far :)
