What is the iconic symbol of Storm?

Superman has the S symbol. Batman has the bat symbol. Captain America has the shield and so on.

But how about Storm?

Is it the white hair?
Is the the eyes all white?
Is it her cape?
Is it the lightning image?
Is it her tiara?
The mohawk look?
Her red ruby?

Something else?

I'd like to add. If you think Storm doesn't have one yet, then what should be her iconic symbol?

I think it's the white hair contrasted with her skin tone. Whenever I see that combo anywhere else I immediately think of Storm. Also, her lightning bolt ear rings are symbolic as well.

White hair, no matter the style.

White hair, They are the symbol Of course.

Being a Black female Mutant...
