I'm assuming the contents of the Title Field have been selected?
The selection color is an OS setting and how you change that depends on your operating system.
If the text here was not selected, then the brown back ground I see is probably a brown rectangle added to this layout and the layout part's fill color is light blue. Enter layout mode, click the part label (body I would guess here), and select a different fill color for it.
Thanks! I forgot to check the OS X appearances system pref. Works fine now after changing it to another color.
