One thing I note is that....her Eyes become Red when she gets really angry. Although she tends to activate her Semblance whenever she's really angry, which could have mislead us.

It could be her eyes only get Red when she's really angry, being irrelevant to her Semblance. This hypothesis can be extended to other "Eyeshifters", if we assume the eyes change color based on emotional state. Wait a minute...

Since volume 3, they've started showing that heightened negative emotion can lead to someone accidentally using their Semblance.

We first saw it with Pyrrha, who was overwhelmed with emotional turmoil over the decision she needed to make. She accidentally used her Semblance to slam Jaune into a wall, then later accidentally used it to temporarily bend her shield and spear.

Now, in volume 4, we saw it with Weiss, who was angry and ended up struggling with Jacques, before accidentally creating a summoning glyph.

So, maybe Yang just has anger issues, and when she gets too angry, she accidentally activates her Semblance.
