Halle Berry to Gabriel Aubry -- You're Trying to Make Our Kid White!

Halle Berry just took Gabriel Aubry to court ... claiming he's trying to make their 6-year-old daughter white.

Halle was furious Gabriel was straightening Nahla's naturally-curly hair, lightening it with highlights and she is convinced it's because he does not want the girl to appear to be African American.

Halle didn't show in court Monday morning, but her lawyer Steve Kolodny did, along with Gabriel and after a lot of arguing the judge ruled NEITHER Halle nor Gabriel could change Nahla's look from its natural state.

So the judge is allowing Nahla's hair to grow back naturally.

Score one for Berry.
