Changing the color of one word in an element type element type "b:widget"

Hi, I have a blog header where the code is <b:widget id='Header1' locked='true' title='alive and Turquoise(Heade r)' type='Header'> <b:includable id='main'>.

I wand to change the color of "Turquoise" only. How can I do it? I try <span> but it says I can't place "<" in a widget.
