Each visual element you see in the repository has a sample application included in the repo. The Crown sample application can be found at the following address:
https://github.com/Taiizor/ReaLTaiizor/blob/develop/demo/ReaLTaiizor.UI/ReaLTaiizor.UI/Form21.cs

Example usage for dark theme:

ReaLTaiizor/demo/ReaLTaiizor.UI/ReaLTaiizor.UI/Form21.cs

Lines 205 to 231 in 2cdd09f

	private void DarkToolStripMenuItem_Click(object sender, EventArgs e)
	{
	ThemeProvider.Theme = new DarkTheme();
	BackColor = ThemeProvider.Theme.Colors.GreyBackground;
	foreach (ToolStripMenuItem Control in mnuMain.Items)
	{
	Control.BackColor = ThemeProvider.Theme.Colors.GreyBackground;
	}
	foreach (ToolStripLabel Control in stripMain.Items)
	{
	Control.ForeColor = ThemeProvider.Theme.Colors.LightText;
	}
	foreach (Control Control in DockPanel.ActiveDocument.Controls)
	{
	if (Control.Name == "txtDocument")
	{
	Control.ForeColor = ThemeProvider.Theme.Colors.LightText;
	Control.BackColor = Color.FromArgb(43, 43, 43);
	}
	}
	Invalidate();
	Refresh();
	}

Example usage for light theme:

ReaLTaiizor/demo/ReaLTaiizor.UI/ReaLTaiizor.UI/Form21.cs

Lines 233 to 260 in 2cdd09f

	private void LightToolStripMenuItem_Click(object sender, EventArgs e)
	{
	ThemeProvider.Theme = new LightTheme();
	BackColor = ThemeProvider.Theme.Colors.GreyBackground;
	foreach (ToolStripMenuItem Control in mnuMain.Items)
	{
	Control.BackColor = ThemeProvider.Theme.Colors.GreyBackground;
	}
	foreach (ToolStripLabel Control in stripMain.Items)
	{
	Control.ForeColor = ThemeProvider.Theme.Colors.LightText;
	}
	foreach (Control Control in DockPanel.ActiveDocument.Controls)
	{
	if (Control.Name == "txtDocument")
	{
	Control.ForeColor = ThemeProvider.Theme.Colors.LightText;
	Control.BackColor = ThemeProvider.Theme.Colors.LightBackground;
	break;
	}
	}
	Invalidate();
	Refresh();
	}

Thanks, so I need to tread each element in the form separately, correct? Is there a theme with default light/dark themes or something built in methods which do this automatically?

Or… Which is a good example c# project I can clone to my VS to see all that in action?
