Help needed with a Regular Expression

Hi,

I need some help to create a regular expression. It is a little like a search and replace, I want to replace any string that contains any substring in parentheses with the same string but the words in parentheses colored RED.

Eg

Take this text in TextBox1:

"The Prime Minister (that idiot from Scotland) made a speech today"

and convert to this text in RichTextBox1:

"The Prime Minister (that idiot from Scotland) made a speech today"

TIA
