We've only seen Yang's eyes turn red when she's angry or using her Semblance on purpose.

Point is, when someone has a large amount of negative emotion, it can cause them to accidentally activate their Semblance. Pyrrha did it, Weiss did it, and Yang has done it many times due to her anger issues.

Yang's eyes turning red when she's angry is not "Oh, her eyes just do that when she's mad." It's "She's so pissed, she accidentally activated her Semblance again."
