LeBron's Black Mask -- NOT FOR WHITE GUYS ... Says NBA Star David Lee

LeBron James' awesome black facemask ain't for everyone .... especially white people ... so says caucasian NBA star David Lee.

The Golden State Warriors big man was boarding the team bus outside the Trump International over the weekend when he told us he was a big fan of LeBron's look.

But Lee admitted he won't be getting a black mask of his own anytime soon ... saying, "I'm a white guy. It wouldn't look right."
