Changing the background color of a Button in Kivy

Question

I\'m new to Kivy and having trouble specifying the background color of a Button. Here\'s my simple example:

# custombutton.py

from kivy.app import App
from          


        

Answer 1

It's been a while since this was first posted so maybe with updates they came up with a better solution:

Button:
    background_normal: ''
    background_color: 1, .3, .4, .85

Since the Button has a default grey, adding background color will only tint the button. By setting background_normal to '' that resets the default to white. From the white canvas the background_color works as you would expect.
