Change button or label text color in kivy

Question

I'm following this kivy book, and while I can understand how to change the background color of buttons, I haven't found the keyword to change the text color.

I saw this and other questions. Here's my code:

#!/usr/bin/kivy import kivy kivy.require('1.7.2')  from random import random from kivy.app import App from kivy.uix.widget import Widget from kivy.uix.gridlayout import GridLayout from kivy.graphics import Color, Ellipse, Rectangle  class MinimalApp(App):     title = 'My App'     def build(self):         root = RootLayout()         return(root)  class RootLayout(GridLayout):     pass  if __name__ == '__main__':     MinimalApp().run() 

and in the .kv file:

#:kivy 1.7.2 #:import kivy kivy  <RootLayout>:     rows: 1     Label:         text: "Why does this not work?" #        rgba: 1,0,1,1                  # doesn't work #        Color:                         # doesn't work #                rgba: 1,0,1,1          # doesn't work #       font_color: rgba: 1,0,1,1         canvas.before:             Color:                 rgba: 0, 0, 0, 1             Rectangle:                 pos: self.pos                 size: self.size 

Answer 1

Use color (all lowercase):

<RootLayout>:     rows: 1     Label:         text: "Why does this not work?"         color: 1,0,1,1 # <-----------         canvas.before:             Color:                 rgba: 0, 0, 0, 1             Rectangle:                 pos: self.pos                 size: self.size
