MDCard's md_bg_color parameter can't be changed during instantiation
I can't change MDCard's md_bg_color parameter during instantiation using MDCard(..., md_bg_color ,...). I checked the source code and in line 24 of card.py, It forces md_bg_color to self.theme_cls.bg_light, I'm new to kivy&kivymd and not quite sure about it. But it works for me if I comment that line.
