This EXACT same thing happened to me in High School circa 1994.
I asked to go on a particular field trip and was informed by a guidance counselor that it was designed for “African American” students.
She didn’t prohibit me from going but strongly persuaded me not to go.

...and if a field trip were for whites only we all know what would’ve happened.
