Colored Hair Extensions, blonde, pink, blue colored hair clip in hair extensions?

I want colored hair extensions.  I'm thinking of getting blonde, pink, and blue.  I want good ones that will last a long time and I also want to be able curl them. Which one of these stores is best? I looked at the colored hair extensions at http://locknlonghairextensions.com/patent/. They have been able to flat iron them and curl them.
