Coloring a line in two different colors

I was wondering how could I color the target's name in red, and everything that follows after in white. The problem is that ColourTell in on a new line, while the target variable might not appear in the beginning of the line.

Have a read of this thread:

In there is a discussion about colouring lines in two colours.

It works, thanks.
