Why does disabled_color not work on the disabled widget? - kivy

Question

I encountered a problem that if I want to make TextInput disabled=True, it repaints the background and font in a grayer color. Background_disabled_normal: '' helped me, and removed color for background, but for font disabled_color does not work at all. The thing is that the TextInput's text appears when the program is running, not during the build phase. How to fix it I don't know)
