UD Route 66 is long discontinued .. but this is gorgeousness in a pot! Route 66 is a gunmetal grey shade with light silver shimmer that makes for a sultry smokey eye. Glides on with nice pigmentation and blends beautifully! A must have if you're looking to expand your smokey eye arsenal!
Route 66 isn't a part of the regular shadow collection. I'm assuming that it was a limited edition shade. Route 66 is a gunmental gray shade. It looks a lot lighter when used as a shadow. I like using this as a liner to also do a smoky eye look.
