How to change color of select item label dynamically?

I can get a select item through the getSelect() API function, however it is not obvious how to find and change the style of the label. I am planning to change the color of a label to red when a form fail validation.

hi

native validation should work this way
the easiest way to change style - myForm.setItemText(name, “Select”)
