Can mixed race people say the N-word?

I'm mulatto, my mum is white and my dad is black I'm not exactly white passing although i have been mistaked for being Caucasian with a tan before? but I don't look fully black either. Black girls tell me I shouldn't say the N-word because I still have the privilege of having lighter skin but other mixed girls say it besides some people are fully black with light skin and I'm sure they still use it.
