In this video I’ll show you two different ways to change the background color of your app with Kivy and Python.

Changing the background color of your app is a pretty fundamental thing in GUI programming and with Kivy it’s pretty easy. I’ll show you how to do it in your Kivy language file using a Canvas and a Rectangle, and I’ll also show you a second way to do it in your actual python file using kivy.core.window

Python Code:
GitHub Code:

from import App
from kivy.uix.widget import Widget
from import ObjectProperty
from kivy.lang import Builder
from kivy.core.window import Window

# Designate Our .kv design file 

class MyLayout(Widget):
class AwesomeApp(App):
	def build(self):
		Window.clearcolor = (1,0,0,1)
		return MyLayout()

if __name__ == '__main__':

Kivy Design Code: bg.kv
GitHub Code: bg.kv

			rgba: (0,0,1,1)
			pos: self.pos
			size: self.size

		orientation: "vertical"
		size: root.width, root.height
		padding: 50
		spacing: 20

			text: "Hello World!"
			text: "Goodbye World!"
