Change color in RichTextBox

I am using this simple example from MSDN to insert lines in a RichTextBox.

FlowDocument myFlowDoc = new FlowDocument();

Run myRun = new Run("This is flow content and you can ");
Bold myBold = new Bold(new Run("edit me!"));

Paragraph myParagraph = new Paragraph();
myParagraph.Inlines.Add(myRun);
myParagraph.Inlines.Add(myBold);

myFlowDoc.Blocks.Add(myParagraph);

RichTextBox myRichTextBox = new RichTextBox();
myRichTextBox.Document = myFlowDoc;

I want to apply a chosed color to the lines of text, but how to do it?

The Paragraph or Run classes doesn't have any direct method to change the color.

EDIT

I don't want to use all the awkard SelectionStart, SelectionEnd stuff as posted on the linked post!.

My case is different and is much more simple: the solution posted from mm8 explains it and is very elegant. One single line of code and that is!

Please see the answer!

The Paragraph or Run classes doesn't have any direct method to change the color.

The Run class inherits from TextElement and this class has a Foreground property that you can set to a Brush:

Run myRun = new Run("This is flow content and you can ") { Foreground = Brushes.Red };
Bold myBold = new Bold(new Run("edit me!") { Foreground = Brushes.Gray });

You can get/set text color via Foreground property of the rich text box. As bellow example, I changed the text color of rich text box to blue:

myRichTextBox.Foreground = Brushes.Blue;

Happy coding!
