    errorColor: "#cf6679",
  },
  themesColors: {
    light: {
      primary: "#6200ea",
      secondary: "#03dac6",
      backgroundColor: "#ffffff",
      buttonColor: "#6200ea",

  const {themeMode, setThemeMode, colors} = useTheme();

  return (
    <View style={{backgroundColor: colors.backgroundColor}}>
      <Button
        title={`Switch to ${themeMode === 'dark' ? 'Light' : 'Dark'} Mode`}
        onPress={() => setThemeMode(themeMode === 'dark' ? 'light' : 'dark')}
